Adjustable Pressure Relief Valve (PRV)

Compatible with hydraulic elevators and VPLs requiring up to 20 GPM flow and pressure regulation between 1,000–2,500 PSI.

Adjustable high-pressure relief valve with 3/4" NPT ports, ideal for safeguarding wheelchair lift hydraulic systems from overpressure conditions.

This universal PRV is a direct-acting, inline hydraulic pressure relief valve designed to protect platform lift components by diverting excess pressure once the set threshold is reached. Its robust construction and adjustable pressure range make it suitable for various hydraulic applications, including accessibility lift systems.

Specifications:

• Maximum flow capacity: 20 GPM
• Adjustable pressure range: 1,000–2,500 PSI
• Factory preset pressure: 1,500 PSI
• Port size: 3/4" NPT female
• Valve type: Direct-acting, ball spring relief
• Construction: Hardened seat for enhanced durability
• Mounting: Inline configuration

Adjustment Instructions:

1. Begin by removing the acorn-style cap nut to access the internal components.

2. Loosen the locking (jam) nut beneath it.

3. Turn the adjustment screw:

   • Clockwise to raise system pressure

   • Counterclockwise to lower system pressure

4. After setting the desired pressure, tighten the jam nut and reattach the acorn cap.

Important Safety Note:
Never adjust pressure blindly. Applying too much pressure can lead to unexpected damage or sudden failure within the hydraulic system. This could result in equipment breakdown or personal injury. Always connect a pressure gauge during adjustments to ensure safe and accurate calibration.
