Unloading valve WJXH.9330A is an important component installed on the hydraulic block of actuator. Its main function is to quickly release the pressure oil in the lower chamber of actuator piston when the unit fails and needs emergency shutdown, or when the emergency tripping device and other actions cause the emergency shut-off oil to leak and lose pressure, so as to ensure the safe and stable operation of the system.

When the unit fails and must be shut down urgently, the unloading valve WJXH.9330A starts quickly, so that the pressure oil in the lower chamber of the actuator piston is quickly released through the quick unloading valve. At this time, regardless of the signal output by the servo amplifier, the valve can be closed under the action of the valve spring force. This process effectively avoids equipment damage caused by the inability to release pressure oil and ensures production safety.

Important role of unloading valve WJXH.9330A

1. Emergency shutdown guarantee: When the unit fails, the unloading valve WJXH.9330A can respond quickly to quickly release the pressure oil in the lower chamber of the actuator piston, ensure the safe shutdown of the unit, and avoid the expansion of the accident.

2. Prevent equipment damage: In the case of emergency oil leakage and pressure loss, the unloading valve WJXH.9330A can quickly unload, avoid pressure oil from damaging the equipment, and reduce maintenance costs.

3. Energy saving and emission reduction: During the unloading process, the unloading valve WJXH.9330A can effectively reduce system pressure, reduce energy loss, and achieve energy saving and emission reduction.

4. Improve system stability: The rapid response of the unloading valve WJXH.9330A in an emergency situation helps to improve the stability of the hydraulic system and ensure smooth production.

As an important component on the hydraulic block of the actuator, the unloading valve WJXH.9330A cannot be ignored in an emergency situation. It is precisely because of its excellent performance and reliability that the unloading valve WJXH.9330A has been widely used in industrial production.
