Two-way Cross-flow Relief Valve
Two-way Cross-flow Relief Valve
Use and operation:
This two-way cross-over relief valve 2 consists of two relief valves with cross-tanks, which are used to block the pressure of two oil ports of an actuator or hydraulic motor to a certain set value. In theory, it can provide protection against sudden pressure fluctuations and can also adjust the different pressures of two oil ports of a hydraulic circuit. The six oil ports (two directions in and four directions out are interchangeable) ensure that only one valve is used for two cylinders.
Application:
Connect V1 and V2 to the pressure flow or an actuator (hydraulic motor). The connection method of the remaining oil ports V1 and V2 is opposite to the former. In order to avoid pressure drops, it is strongly recommended to install on the actuator.
