DESCRIPTION

Pilot-operated, pressure reducing valves reduce a high primary pressure at the inlet (port 2) to a constant reduced pressure at port 1, allowing circuits with multiple pressure requirements to be operated using a single pump.

 

OPERATION

The 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. 

All three-port pressure reducing and reducing/relieving cartridges are physically interchangeable (i.e.same flow path, same cavity for a given frame size). When considering mounting configurations, it is sometimes recommended that a full capacity return line (port 3) be used with reducing/relieving cartridges. 

FEATURES

* Pilot operated valves exhibit exceptionally flat pressure/flow characteristics. 

* Are very stable and have low hysteresis. 

* Factory Pressure Settings Established at: blocked control port (dead headed)

* Pressure at port 3 is directly additive to the valve setting at a 1:1 ratio and should not exceed 350 bar (5000 psi).
