SEQUENCE VALVE

Overview

Description

PS10-32 is a screw-in, cartridge style, direct-acting, spool-type, hydraulic sequence valve with external pilot and internal spring chamber drain, designed to direct flow to a secondary circuit once a predetermined pressure level is attained in the primary circuit

Operation

In its steady state, the PS10-32X blocks flow from port 3 to port 2. On attainment of a pre-determined pressure at port 1, the cartridge shifts to open port 3 to port 2. Since the spring chamber is vented at port 2, back pressure at port 2 will directly (1:1) affect the valve's setting

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.
