PRESSURE SEQUENCE VALVE

Overview

Description

The PS10-43X is a spool type, pilot operated, hydraulic sequence valve with external pilot and internal spring chamber drain. It is designed to function as a remote pilot-operated three-way valve.

Operation

In neutral (unpiloted), the PS10-43X allows flow to pass bidirectionally from port 3 to port 2, while blocking at port 4. The spring chamber is constantly drained at port 4. Upon attainment of a predetermined pressure at port 1, the spool shifts to close port 3 to port 2, while opening port 3 to port 4.

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.
