PR10-36

PRESSURE REDUCING/ RELIEVING CARTRIDGE VALVE U.S. PATENT # 7,137,406

Overview

Description

The pr10-36xx 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.

Operation

In its steady state, the pr10-36xx 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.

Features

  • Adjustments cannot be backed out of the valve.
  • Adjustments prohibit springs from going solid.
  • Optional spring ranges to 207 bar (3000 psi).
  • Hardened spool and cage for long life.
  • Industry-common size.
