DESCRIPTION
A screw-in, cartridge-style, direct-acting, spool-type reducing/relieving valve 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 PRES50-30 allows bidirectional flow from 3 to 2 with the spring chamber constantly drained at 1. Upon attainment of a predetermined pressure at 2, the valve will shift to block flow at 3, thereby regulating pressure at 2. In this mode, the valve will also relieve port 2 to port 1 at a variable value over the set reducing pressure.
The tank port pressure is additive to the pressure setting at a ratio of 1:1..
FEATURES
• High Pressure steel adapter on inlet port 3 withstands up to 345 bar (5000 psi).
• Hardened spool and cage for long life.
