Ventable Relief valves (RV) and Sequence Valves (SP)

Related Classifications: hydraulic valves, hydraulic pneumatic speed control check valves, hydraulic spool valve

A Ventable Relief Valve (RV) is a type of relief valve used to:

• Act as safety valves. They protect fixed displacement pumps and directional control valves when pump output flow is intermittently blocked.
• Limit pressure overshoot associated with pressure compensated pumps.
• Protect hydraulic actuators (cylinders & motors) from shock pressures associated with starting and stopping heavy loads.

Original Press Release

A Ventable Relief Valve (RV) is a type of relief valve used to:

• Act as safety valves. They protect fixed displacement pumps and directional control valves when pump output flow is intermittently blocked.
• Limit pressure overshoot associated with pressure compensated pumps.
• Protect hydraulic actuators (cylinders & motors) from shock pressures associated with starting and stopping heavy loads.

Specifications of RV:

• Rated flow of up to 480 LPM
• Maximum pressure of 420 Bar
• Special features of RV:
• Port 3 allows an RV to be remote controlled or to be used for pump unloading

Main uses of Sequence Valves (Pilot Operated and Direct Acting):

• Operations where two or more components in a circuit are needed to move in a planned sequence. SPs control the sequence of two or more cylinders or motors while maintaining pressure on the actuator that moves first.
• To assure that one circuit is pressurized before a second circuit.

Specifications of SP:

• Rated flow of up to 480 LPM
• Maximum pressure of 420 Bar

Special Features of SP:

• normally closed
• pressure operated, opens at an adjustable pressure setting
• poppet/spool valves
• Inclusion of an external drain in an SP’s structure to trap leaked oil, which limits malfunction to modification of set pressure and prevents the valve from opening
• Direct Acting Sequence valves with reverse check are also available.
