DESCRIPTION
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 1 or 3 port to the 2 port.
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.
