The Yale VPR-1 is an adjustable hydraulic pressure relief valve with control range 0 to 700 bar, used when system pressure (the force of the connected cylinder) should not exceed a certain value. Yale specifies this as a precision valve with easy adjustment and high precise repetition.

Adjustable pressure relief for custom hydraulic systems

Yale documentation states the VPR-1 is used when system pressure should not exceed a certain value. After the set pressure is reached, excessive oil is guided back to the reservoir pressureless. Yale notes that for pressure relief valve selection only the displacement of the high pressure stage matters, so size the VPR-1 to match your pump's high-pressure flow.

Suitable Applications

Per Yale: custom hydraulic system protection, hydraulic test rigs, and Yale's own power pack configurations alongside VHP-4/3 directional valves and VSM-21 safety check valves.

Valves must share the system pressure rating with the pump and cylinder — the circuit is limited by its lowest-rated component.

Frequently Asked Questions

Q: How do I size the VPR-1 for my pump?

Match the VPR-1's 10 l/min flow capacity to your pump's high-pressure stage flow. Yale notes that for pressure relief valve selection only the displacement of the high pressure stage matters.

Q: Where does relieved oil go?

Yale specifies the relieved oil is guided back to the reservoir pressureless via the T port. Connect T to the reservoir return line without back pressure.
