Elevator Valve Repair & Replacement

Valves are essential parts of any hydraulic elevator system and, like other components, may occasionally require repair or replacement. If you encounter a malfunctioning valve, seek professional assistance right away, as it can pose safety risks and disrupt operations.

What does elevator valve repair or replacement entail?

Elevator valve repair involves fixing or maintaining the hydraulic valve system that controls the movement of the elevator. The valve regulates the flow of hydraulic fluid, which determines how smoothly the elevator starts, stops and changes speed.

Identifying and fixing valve issues early can prevent more costly damage to the hydraulic system or other parts of the elevator.

Common Types of Valve Problems

Valve issues may cause:

Poor leveling: This means the elevator does not stop level with the floor, which can cause tripping hazards for passengers.
Poor ride quality: A faulty valve can cause sudden jerks or vibrations, leading to an uncomfortable and potentially dangerous ride.
Abrupt transitions during starting and stopping: Much like poor ride quality, a faulty valve can lead to abrupt or jarring movements when the elevator starts or stops, rather than providing smooth, gentle transitions. This can make the ride feel unstable and may cause discomfort or even minor injuries to passengers if they’re unprepared for the sudden movement.

Repair vs. Replacement

It’s an age-old question in the world of manufacturing and technology: When is it better to repair instead of replace?

The decision when it comes to elevator valves depends on a number of factors, including the age of the elevator system, long-term cost implications and the extent of the damage. Was there a specific issue with the elevator tank, or is the system simply in need of cleaning?

In Massachusetts, for example, when replacing a valve, you’re required to conduct a valve test with an inspector, which adds time and cost to the project. However, if a valve can be repaired rather than replaced, this inspection isn’t necessary, saving both time and money. Repairs are typically quicker and less costly than replacements, making them a more budget-friendly option when feasible. Stanley Elevator specializes in diagnosing elevator issues, helping you determine whether repair or replacement is the best approach for your situation.

The Valve Repair Process

The timeline for valve repair or replacement can vary based on specific circumstances, but Stanley Elevator is committed to completing the job as efficiently as possible. Our team will coordinate with you every step of the way to minimize downtime and ensure your elevator is up and running promptly.

Here’s an overview of the process:

Diagnose and troubleshoot: This involves checking the system, inspecting the valve and testing the valve pressure.
Prepare for repairs: Once we discover what’s wrong, we take the appropriate safety measures to begin the repair or replacement process, including draining the hydraulic fluid.
Disassemble the valve: We carefully disassemble the valve to examine the internal components. This includes removing any bolts, seals or connectors.

Clean and inspect all parts of the valve: We remove all dirt, debris and old sealant and also conduct a comprehensive inspection that includes looking for wear, corrosion and any signs of damage.

Replace damaged parts: We’ll replace any parts that show significant wear, such as seals or springs. SECO will notify you if existing conditions require replacement of the valve rather than repair.
Reassemble the valve: Once we replace any damaged parts, we carefully reassemble the valve and ensure everything is correctly aligned and properly sealed.

Filter oil and return to the tank as needed: We can also filter and clean the hydraulic oil before returning it to the system.

Test the valve: We thoroughly test the reassembled valve to ensure it’s functioning properly. This includes checking for leaks, verifying the pressure settings and ensuring it’s operating as intended. If necessary, perform tests as required with local AHJ.
Conduct a final check: We complete the process with a comprehensive final inspection to ensure that everything is functioning properly and that the valve repair or replacement has been successful.
