SEQUENCE VALVE, PILOT OPERATED U.S. PATENT # 7,137,406

Overview

Description

The GPS50-36X is a spool type, pilot operated, adjustable, internally piloted, externally vented, hydraulic sequence valve.

Operation

It is designed to direct flow from port 1 to port 2 once a predetermined pressure is attained in a circuit. the valve will remain shifted until the pressure in the circuit falls below the pressure setting.

Features

  • Adjustments cannot be backed out of the valve
  • Adjustments prohibit springs from going solid
  • Optional spring ranges to 345 bar (5000 psi)
  • Hardened spool and cage for long life
  • Industry-common size
