At CED Elevator & Electrical, we also look beyond the valve itself. The pump, motor, reservoir, oil condition, temperature control, cylinder packing, and electrical controls all influence how smoothly a hydraulic elevator starts, levels, and stops.

Maxton vs. EECO vs. Texacone: What Is the Difference?

This distinction matters when troubleshooting a rough ride.

A technician may initially suspect the valve when the actual problem is cylinder friction, worn packing, contaminated oil, incorrect temperature, or a control-sequence issue.

Maxton Hydraulic Valves: Strong Adjustment and Support Options

Maxton manufactures hydraulic elevator control valves including UC-series mechanical valves and electronic options. Its published procedures cover bypass, acceleration, transition, leveling speed, stopping, relief settings, and troubleshooting.

Maxton also emphasizes that valve procedures are intended for skilled hydraulic elevator professionals. Its documentation notes that proper valve adjustment affects ride quality, pump performance, motor performance, and overall system efficiency.

Technicians searching for a Maxton valve adjustment guide should always identify the exact valve model before making changes. UC1, UC2, UC4, UC4M, UC4MR, and electronic valve procedures are not interchangeable.

The official Maxton valve adjustment procedures provide model-specific technical references.

When We Consider Maxton

Maxton can be a strong choice when a project requires:

• Predictable leveling control
• Replacement of an aging hydraulic valve
• Readily available service information
• Rebuild and maintenance components
• Compatibility with common hydraulic power-unit configurations

EECO Hydraulic Valves: Broad Application Range

EECO also produces dedicated hydraulic elevator control valves.

Its current catalog includes valve families for residential, LULA, and commercial applications. EECO states that valve adjustment should be performed by qualified hydraulic elevator professionals and recommends clean hydraulic oil with proper filtration.

Some EECO designs incorporate temperature compensation to help maintain more consistent operation as hydraulic oil viscosity changes.

That can be important because hydraulic elevator behavior can change as the machine room and oil move from a cold morning startup to sustained operation later in the day.

When EECO Makes Sense

We may evaluate EECO when:

• Replacing an existing EECO valve
• Matching a particular flow requirement
• Retaining familiar field-service components
• Modernizing an older hydraulic installation
• Temperature consistency is a major concern

The correct selection should always be based on actual job data rather than choosing a manufacturer by brand name alone.

Where Texacone Fits

Texacone should not be treated as a direct Maxton or EECO valve competitor.

Its products focus heavily on hydraulic elevator cylinder heads, packing sets, seals, alignment, sanding, and repair solutions. CED carries Texacone products such as Sure-Fit repair components, alignment systems, sanding sleeves, O-ring splicing products, and cylinder-head identification resources.

That becomes important when poor leveling is actually caused by friction at the cylinder.

Texacone notes that cylinder misalignment, damaged plungers, temperature extremes, and packing conditions can contribute to leakage or excessive friction.

A perfectly adjusted control valve cannot fully compensate for a mechanical cylinder problem.

What Causes a Hydraulic Elevator Valve to Leak?

A hydraulic elevator valve leaking internally or externally may involve several different conditions.

Common troubleshooting areas include:

• Contamination around valve seats
• Worn seals or O-rings
• Damaged solenoid components
• Worn pistons or guides
• Incorrect relief settings
• Contaminated hydraulic oil
• Cylinder packing leakage
• Improper valve sizing
• Excessive operating temperature

Maxton’s troubleshooting documentation specifically identifies debris, damaged valve components, worn seals, and contaminated strainers as possible causes of poor operation and drift.

Rather than repeatedly adjusting a valve to compensate for another fault, we prefer diagnosing the complete hydraulic system.

Hydraulic Oil Temperature Can Change Leveling

Oil viscosity changes with temperature.

When a hydraulic elevator runs too hot or too cold, technicians may see changes in acceleration, leveling, stopping, noise, or ride consistency.

That is where an elevator hydraulic oil cooler or tank heater may become part of the solution.

CED hydraulic power units can be configured with optional oil coolers, tank heaters, pressure gauges, low-oil switches, low-pressure switches, scavenger pumps, and other accessories.

For buildings with high elevator usage or machine-room temperature swings, stabilizing oil temperature can help maintain more predictable hydraulic performance.

Know the Hydraulic Elevator Power Unit Components

The valve does not work alone.

The four primary hydraulic elevator power unit components are:

1. Reservoir to hold hydraulic oil
2. Pump to move oil into the cylinder
3. Motor to drive the pump
4. Control valve to regulate flow, acceleration, leveling, and stopping

CED explains these components in our hydraulic elevator power unit guide.

A leveling complaint can originate from any part of that system.

Rebuild the Valve or Replace It?

A rebuild may make sense when the valve body remains serviceable and the problem is isolated to replaceable seats, seals, coils, solenoids, or internal components.

Replacement deserves consideration when:

• Valve wear is extensive
• Adjustment no longer produces stable operation
• Parts availability is becoming difficult
• The power unit is undergoing modernization
• Flow requirements have changed
• Repeated callbacks outweigh repair cost

Maxton documentation even recommends considering valve overhaul or replacement on a periodic basis when adverse operating conditions are present.

Selecting the Right Hydraulic Elevator Components

At CED Elevator & Electrical, we supply hydraulic elevator components for contractors working on repairs, modernization, and complete power-unit projects.

Rather than treating Maxton, EECO, and Texacone as interchangeable products, we match the actual problem to the right component. That may mean a control valve, rebuild kit, cylinder packing, oil cooler, heater, pump, motor, or complete hydraulic elevator power unit.

For technicians sourcing direct replacement parts, having the valve model, serial number, flow requirement, pressure, oil type, motor data, and existing power-unit information available can make component selection much faster.

For 2026, the most important step is simple: do not wait for a failed inspection to find out your elevator is behind.

The ASME A17.1/CSA B44 Safety Code is widely recognized across North America for elevator design, installation, operation, inspection, testing, maintenance, alteration, and repair. ASME A17.1-2025 has been published, and local adoption timelines may vary by jurisdiction. Building owners should always confirm which code edition is enforced in their state, county, or city.

At CED Elevator & Electrical, building teams can source elevator parts, modernization packages, service materials, controllers, cables, fixtures, wire rope, power units, and repair components that support safe and compliant operation.

Why Elevator Safety Code Compliance Matters

Elevator code compliance is not just a paperwork issue. It affects passenger safety, tenant trust, liability, building access, and operating continuity.

A missed inspection, expired permit, failed emergency phone, outdated controller, or non-compliant cab feature can create avoidable risk. For commercial buildings, hospitals, schools, multifamily properties, offices, and public facilities, elevators are part of daily life.

A good compliance plan protects:

• Passenger safety
• ADA accessibility
• Emergency response
• Inspection readiness
• Permit renewal timelines
• Tenant confidence
• Long-term equipment performance

1. Know Your Local Elevator Inspection Requirements

Elevator inspection requirements are enforced locally. Your building may need annual inspections, periodic testing, correction reports, permit renewals, and documentation for maintenance or alterations.

Before 2026, building owners should ask:

• When is the next required elevator inspection?
• Is the elevator permit current?
• Are past violations fully corrected?
• Is testing documentation complete?
• Are maintenance records easy to access?
• Are replacement parts available if repairs are needed?

CED’s Service and Repair division stocks parts from more than 100 manufacturers and supports repair needs for down elevators, including electrical, GAL replacement parts, batteries, fans, coolers, and Texacone packing.

2. Review ADA Compliant Elevator Features

ADA compliant elevators must be usable by people with disabilities. The 2010 ADA Standards set minimum accessibility requirements for newly constructed or altered public accommodations, commercial facilities, and state and local government facilities.

Building owners should review:

• Button height and reach range
• Braille and tactile markings
• Visual and audible signals
• Hall and cab fixtures
• Door timing
• Clear floor space
• Emergency controls
• Communication accessibility

If your elevator cab or fixtures are outdated, modernization may be a better solution than full replacement. CED’s Modernization offerings include hoistway and traveling cable, wire rope, hydraulic fittings, SmartRise Controllers, GAL Canada Linear Door Operators, and ECC hall and cab fixtures.

3. Upgrade Emergency Communication Systems

Emergency communication systems are a major compliance focus. The U.S. Access Board notes that ASME A17.1 requires a two-way means of emergency communication in elevator cars.

Newer code discussions also focus on communication access for passengers who are deaf, hard of hearing, or speech impaired. NEII explains that IBC requirements address elevator emergency communication systems for deaf, hard of hearing, and speech impaired passengers, while ASME A17.1 technical provisions help guide consistent application.

Building owners should check whether the elevator communication system:

• Connects reliably to authorized personnel
• Works during power or phone system changes
• Supports required voice, visual, or text communication
• Is tested and documented
• Matches the code edition enforced locally

4. Do Not Ignore Elevator Permit Renewal

Elevator permit renewal is often where compliance problems surface. If records are missing, inspections are overdue, or violations remain unresolved, renewal can become stressful.

Create a simple compliance file that includes:

• Current elevator permit
• Inspection reports
• Test records
• Maintenance Control Program documents
• Violation corrections
• Modernization records
• Emergency phone test logs
• Component replacement records

This makes inspections easier and gives owners peace of mind.

5. Use Modernization to Close Compliance Gaps

Not every compliance issue requires a full elevator replacement. Many buildings can improve safety, performance, accessibility, and reliability with targeted commercial elevator upgrades.

Modernization may include:

• Controller upgrades
• Door operator replacement
• Cab fixture updates
• Emergency communication upgrades
• Traveling cable replacement
• Wire rope replacement
• Hydraulic power unit components
• Lighting and cab interior improvements

CED has supplied elevator modernization materials for more than 25 years and provides parts for modernization, construction, OEM, service, and repair needs.

Safety Codes FAQs

What elevator safety code should building owners know for 2026?

Building owners should understand ASME A17.1/CSA B44 and confirm which edition their local jurisdiction enforces.

How often do elevators need inspections?

Inspection schedules vary by state and local authority. Owners should check local elevator inspection requirements and keep permits, reports, and testing records current.

What makes an elevator ADA compliant?

ADA compliant elevators include accessible controls, tactile and braille markings, visual and audible signals, proper door timing, and emergency communication access.

Can modernization help with compliance?

Yes. Controller upgrades, fixtures, emergency communication systems, door operators, cables, and cab improvements can help address safety, accessibility, and performance gaps.

At Consolidated Elevator Distributors (CED), we’ve spent years helping professionals navigate the elevator modernization process. Replacing an entire system is a massive capital expense, but strategic component upgrades can often achieve the same results for a fraction of the cost.

1. The Brains of the Operation: Controller Upgrades

If your elevator is experiencing frequent “brain farts”—unleveling, erratic door behavior, or long wait times—it’s usually a controller issue.

Instead of a full replacement, a modernization kit focusing on the controller can revolutionize performance. At CED, we advocate for non-proprietary elevator controllers.

• Why it matters: Proprietary parts lock you into a single manufacturer for life. Non-proprietary parts give you the freedom to choose your service provider, lowering long-term maintenance costs.
• The Result: Improved energy efficiency, smoother acceleration/deceleration, and significantly reduced downtime.

2. Door Systems: Solving the #1 Cause of Service Calls

Statistically, nearly 70% of elevator service calls are door-related. Before you rip out the whole car, look at the door operator.

Modernizing your door equipment with high-performance operators and infrared light curtains (safety edges) does two things:

1. Enhances Safety: Newer sensors are far more sensitive to obstructions, reducing liability.
2. Increases Speed: Modern harmonic motion operators open and close more efficiently, improving “floor-to-floor” time.

3. Aesthetics and the “Tenant Perception” Factor

Sometimes, an elevator works fine, but it looks like a time machine from 1984. Passenger perception is reality when it comes to property value.

Upgrading your fixtures, such as Car Operating Panels (COP) and hall lanterns, is the quickest way to boost the perceived value of your building.

• ADA Compliance: Modern fixtures ensure you meet current accessibility standards.
• Touchless Tech: In a post-pandemic world, touchless buttons and antimicrobial finishes remain high-value features for tenants.

4. Safety Gear and Code Compliance (A17.1)

Safety isn’t just a benefit; it’s a legal requirement. If your system is struggling to meet current A17.1 code compliance, you don’t necessarily need a new elevator, but you likely need new safety components.

Key upgrades to consider include:

• Governor Tensioners: Essential for overspeed protection.
• Pit Buffers: The final fail-safe for car impact.
• Emergency Brake Systems: A must-have for preventing unintended car movement.

Which Path is Right for Your Building?

The “Roadmap” depends on the age of your equipment and your long-term goals. If the “bones” (the rails and the car frame) are solid, modernization is almost always the more sustainable and cost-effective choice.

The Function of a Hydraulic Elevator Power Unit

In simple terms, the power unit provides the force that lifts and lowers the elevator car. It consists of four primary components:

1. Tank (Reservoir): Holds the hydraulic oil that drives the system.
2. Pump: Typically a screw pump, it pushes oil into the cylinder to raise the elevator.
3. Motor: The submersible motor powers the pump, converting electrical energy into mechanical pressure.
4. Valve: The valve controls oil flow, ensuring smooth starts, stops, and leveling accuracy.

When the elevator is called to a higher floor, the pump forces hydraulic oil into the cylinder, raising the piston and car. When descending, the Maxton valve precisely releases oil back into the tank, allowing for controlled lowering.

This balance of power, flow, and control is what gives hydraulic elevators their signature smooth ride.

Why Quiet Operation Matters

While all hydraulic elevator power units produce some noise, CED Elevator & Electrical’s units are engineered to run quieter thanks to their construction. The reduced noise doesn’t come from the pump, motor, or valve alone — it comes from the way the entire unit is built.

Each tank incorporates welded Unistrut across the full width of the front and back to increase rigidity and reduce vibration. The ½-inch thick motor mounts are isolated and anchored to the Unistrut, minimizing vibration transfer through the frame. The thick-gauge steel tank features a flat bottom that holds more oil, improving sound dampening and temperature stability. Even the lid is engineered to avoid metal-to-metal contact, reducing resonance during operation.

These structural features significantly reduce noise and vibration. It’s one more reason installers and building owners appreciate the quality behind a CED Elevator & Electrical hydraulic power unit.

Reliability and Ease of Maintenance

Each component in a CED power unit is chosen for long-term reliability and easy serviceability. The steel tank design includes a hinged and shocked lid for one-hand opening, and a cutout for quick and easy access to the valve, while optional features like oil coolers, scavenger pumps, and pressure gauges make it adaptable to a variety of installation needs.

Replacement parts and support are available through CED Elevator & Electrical’s nationwide branch network, minimizing downtime and keeping maintenance simple.

Trusted Brands, Proven Components

Our units are built with components from some of the most trusted names in the elevator industry:

• Seim Pumps — known for precision, quiet operation, and long life.
• Imperial Electric Motors — delivering consistent performance and efficiency.
