Load Shuttle Valve
QCV08-30 = Ball shuttle valve =
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.
The QLS08-30 will allow flow from the higher pressure of ① or ③ port to the ②port. The valve is commonly used to direct oil from the pressure side of a bidirectional hydraulic motor to a pressure-released hydraulic brake.
