DESCRIPTION
The E-PR08-32 is a screw in, cartridge style, direct acting, spool type, hydraulic pressure reducing/relieving valve with internal pilot and internal spring chamber drain. It is designed to act as a pressure regulating device for secondary circuits. It is intended for use in stable input flow circuits.

OPERATION

In its steady state, the E-PR08-32 allows flow bidirectionally from port 2 to port 1, with the spring chamber constantly drained at port 3. On attainment of a pre-determined pressure at port 1, the cartridge shifts to block flow at port 2, thereby regulating pressure at port 1. In this mode, the valve will also relieve port 1 to port 3 at a variable value over the set reducing pressure.
Note: Direct-acting PR series valves may not be suitable for some static load applications. 

FEATURES
* Adjustments cannot be backed out of the valve. 
* Adjustments prohibit springs from going solid.
* Optional spring ranges to 152 bar (2200 psi)
* Hardened spool and cage for long life. 
* Industry common cavity. 
* Compact size.
