Our Gas-over-oil Actuator is designed on the basic of our experience on Electric actuator and Electro hydraulic actuator, referring to international advanced actuator technology. It is mainly used in river crossing valve room, Station By-pass valve, Station Entrance/Exit Protection, Long distance pipeline, compressor load/unload protection, stand blowdown, emergency shutdown, line break protection, remote control, etc.

The line break protection gas over oil actuator is designed on the basic of standard actuator, can close the pipe when any pipe leakage detected. Actuator has 3 group pressure sensor, provide higher reliability on detecting pipe pressure change and protection. Our actuator has passed explosion proof and SIL approval, are widely used in China, Russia, Pakistan and other countries.
