YFL Pneumatic-hydraulic gas over oil actuators are installed on emergency shut down valves in long distance petroleum and natural gas pipeline to monitor the pipeline pressure and close the valves automatically when there is urgent situation to avoid accident.

There may be fracture, leakage or even explosion happen to long distance pipeline for oil, gas or hazardous chemical goods duo to construction, earthquake or fire. So it is very important to use ESD valves equipped with pneumatic-hydraulic gas over oil actuators to reduce the accident risk and loss.

The gas pressure of the natural gas pipeline is the power of pneumatic-hydraulic gas over oil actuator to realize control and operation.
