LS50-30

LOAD SHUTTLE VALVE

Overview

Description

The LS50-30 is 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 LS50-30 will allow flow from the higher pressure of port 1 or port 3 to port 2

Features

  • Rapid response to load direction changes.
  • Industry-common cavity.
