E-PPDF Pilot-operated, pressure reducing/relieving valve with drilled piston orifice
SYMBOL
OPERATION
Pilot-operated, pressure reducing/relieving valves reduce a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1, with a full-flow relief function from port 1 to tank (port 3).
FEATURES
* Full reverse flow from reduced pressure (port 1) to inlet (port 2) may cause the main spool to close. If reverse free flow is required in the circuit, consider adding a separate check valve to the circuit.
* Pilot operated valves exhibit exceptionally flat pressure/flow characteristics, are very stable and have low hysteresis.
