LS04-B30

LOAD SHUTTLE VALVE

Overview

Description

The LS04-B30 is a load-shuttling, 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 LS04-B30 will allow flow from the higher pressure of port 1 or port 3 to the port 2. The valve is commonly used to direct oil from the pressure side of a bidirectional hydraulic motor to a pressure- released hydraulic brake. It CAN also be used as a load-sense signaling valve

Features

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