SEQUENCE VALVE

Overview

Description

The PS10-40X is a spool type, direct acting, adjustable, external pilot hydraulic sequence valve with externally vented spring chamber

Operation

The PS10-40X blocks flow between ports 2 and 3 bidirectionally. The spring chamber is constantly vented at port 4. On attainment of the valve pressure setting at port 1, the spool shifts to open ports 2 and port 3 bidirectionally. Pressure at port 4 is additive to the spring setting at a 1:1 ratio

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.
