SEQUENCE VALVE

Overview

Description

The PS10-41X is a spool-type, direct-acting, adjustable, normally open, hydraulic sequence valve with external pilot and spring chamber drain.

Operation

The PS10-41X is designed to block flow between port 2 and port 3 once a predetermined pilot pressure is attained in a circuit. The valve will remain shifted until the pressure in the circuit falls below the pressure setting or spring chamber pressure added to the valve exceeds pilot pressure.

Features

  • Adjustments cannot be backed out of the valve.
  • Adjustments prohibit springs from going solid.
  • Optional spring ranges to 151.7 bar (2200 psi).
  • Hardened precision spool and cage for long life.
  • Industry-common size.
