DESCRIPTION
The E-PR12-36 is a spool type, pilot operated, hydraulic pressure reducing/relieving valve with internal pilot and internal spring chamber drain, designed to act as a pressure regulating device for secondary circuits.
OPERATION
In its steady state, the E-PR12-36 allows flow to pass bidirectionally from port 2 to port 1, with the spring chamber constantly drained at port 3. Upon attainment of a predetermined pressure at port 1, the spool shifts to restrict inlet flow from port 2, thereby regulating pressure at port 1. In this mode the valve will also relieve port 1 to port 3.
Flow Path: Reducing: 2 to 1; Relieving: 1 to 3.
FEATURES
* Adjustments cannot be backed out of the valve.
* Adjustments prohibit springs from going solid.
* Optional spring ranges to 207 bar (3000 psi).
