* Brake valve Overview This brake valve is an arbitrary combination of the direct operated type relief valve, check valve, bypass valve and so on, and is used to eliminate shocks that occur when an actuator such as a hydraulic motor starts and stops. Features 1. As the direct operated type relief valve is used, the responsiveness is good and the internal leakage amount is small. 2. There are a variety of circuit types.

Brake valve<br />
Overview<br />
This brake valve is an arbitrary<br />
combination of the direct operated type<br />
relief valve, check valve, bypass valve and<br />
so on, and is used to eliminate shocks that<br />
occur when an actuator such as a<br />
hydraulic motor starts and stops.<br />
Features<br />
1. As the direct operated type relief valve is used,<br />
the responsiveness is good and the internal<br />
leakage amount is small.<br />
2. There are a variety of circuit types. (with bypass<br />
valve, with check valve for anti-cavitation)<br />
