SEQUENCE VALVE

Overview

Description

The PS10-31X is a screw-in, cartridge style, direct acting, spool type, hydraulic sequence valve with internal pilot and spring chamber drain. It is designed to direct flow to a secondary circuit once a predetermined pressure is attained in the primary circuit.

Operation

In its steady state, the ps10-31x blocks flow at port 1, while allowing flow between port 2 and port 3. On attainment of a predetermined pressure at port 1, the valve shifts to open port 1 to port 2 and to close port 3.

Features

  • Adjustments cannot be backed out of the valve.
  • Adjustments prohibit springs from going solid.
  • Optional spring ranges to 144.8 bar (2100 psi).
  • Hardened spool and cage for long life.
  • Industry-common size.
