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. (with bypass
valve, with check valve for anti-cavitation)
