HydraForce PR50-36 Pressure Reducing / Relieving Valve


The HydraForce PR50-36 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. Port 2 may be protected by 60 mesh, 250 micron rated screen with option S.

In its steady state, the PR50-36XX 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.

Key features:

  • Adjustments cannot be backed out of the valve.
  • Adjustments prohibit springs from going solid.
  • Optional spring ranges to 345 bar (5000 psi).
  • Hardened spool and cage for long life.
  • Industry-common size.

Pressure ratings:

  • Pressure rating: Port 1 and Port 2, 344.7 bar (5000 psi) and Port 3, 69 bar (1000 psi)
  • Proof pressure: 482.6 bar (7000 psi)
  • Burst pressure: 965.3 bar (14000 psi)

Flow rating: 56.8 lpm (15 gpm)

This valve can be used with mineral based or synthetic hydraulic fluid with lubricating properties
