Overview

Description

PS10-33X is a screw in, cartridge style, direct acting, spool type hydraulic sequence valve with external pilot.

Operation

The PS10-33X blocks flow from port 3 to port 2 until sufficient pressure is present at port 1 to shift and allow flow from port 3 to port 2.

Features

  • Adjustments cannot be backed out of the valve.
  • Adjustments prohibit springs from going solid.
  • Optional spring ranges to 240 bar (3500 psi).
  • Hardened spool and cage for long life.
  • Industry-common size.
