PRES50-30 is a screw in, cartridge style, direct-acting, spool-type, hydraulic pressure reducing/relieving valve designed to act as a pressure regulating device for secondary circuits. It is intended for use in stable input flow circuits.
In its steady state, the PRES50-30 allows flow to pass bidirectionally from port 3 to port 2 with the spring chamber constantly drained at port 1. Upon attainment of a predetermined pressure at port 2, the cartridge shifts to block flow at port 3, thereby regulating pressure at port 2. In this mode, the valve will also relieve port 2 to port 1 at a variable value over the set reducing pressure.
note: tank port pressure is additive to valve setting at ratio of 1:1.
- High Pressure steel adapter on inlet port 3 withstands up to 345 bar (5000 psi).
- Hardened spool and cage for long life.
