PK80 with Automatic Kickout Feature

Directional control valves are one of the core elements in a hydraulic circuit. They help directing the fluid to different components in the system. Hidros provide monoblock, sectional, and solenoid-operated spool type control valves with different flow capacities and spool options

Description

These valves are for use in a machine having a part moved by hydraulic pressure under control of a manual control valve which has a detent for holding it in an actuating position. The kickout valve is engaged when the movable part reaches a pre-established position. The valve is opened and admits fluid under pressure through a circuit leading to the control valve, where it causes release of the detent and allows the control valve to seek a closed or hold position and the moving part to come to rest.
