LS04-B30 (LS04-B30)
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.
Product Operation
The LS04-B30 will allow flow from the higher pressure of ➀ or ➂ port to the ➁ 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.
Product Features
• Rapid response to load direction changes.• Miniature size.
