Hongxun oil pneumatic surface safety valve

Short Description:

A pneumatic safety valve is a device that is used to protect pneumatic systems from excessive pressure. It automatically opens and releases the accumulated pressure when it exceeds a predefined level, ensuring the safety and integrity of the system. These valves are crucial in preventing accidents or damages caused by overpressure, which could result in explosions or system failures.

The valve is used in conjunction with an emergency shut down system (ESD) and normally installed upstream of the choke manifold. The valve is remotely operated either manually by push button or automatically triggered by high/low pressure pilots. When a remote station is activated the emergency shut down panel acts as a receiver for the air signal. The unit translates this signal into a hydraulic response which bleeds the control line pressure off of the actuator and closes the fail closed valve.
