LOAD SHUTTLE VALVE

Overview

Description

A load shuttle, screw-in, cartridge style, hydraulic check valve, for use in blocking circuits where a priority of flow/direction is given to a higher pressure circuit over a lower one.

Operation

The LS08-30 will allow flow from the higher pressure port 1 or 3 to port 2.

Features

  • Rapid response to load direction changes.
  • Compact size.
