It is a self operated actuator that utilizes the pressure of the pipeline's own medium to drive valve action, achieving valve opening or closing. The working principle of the pneumatic hydraulic actuator is simple, the control is safe and reliable, and the environmental adaptability is strong, which can meet the harsh all-weather weather conditions outdoors.
This product directly uses pipeline natural gas as its power source. The pneumatic hydraulic system is designed for high pressure, and the air source is filtered and processed without pressure reduction, directly entering the air storage tank and high-pressure pneumatic control valve group. Under the control signal, high-pressure controlled gas enters the corresponding gas/liquid circuit, and the liquid medium uses the principle of equal pressure transmission to achieve gas-liquid synchronous transmission action for the hydraulic cylinder of the valve driving device, thereby controlling the valve.

Pressure is power "is a concise and perfect interpretation of the working principle of pneumatic hydraulic actuators. The pressure of natural gas in pipelines is the driving force used by pneumatic hydraulic actuators to complete control and achieve switching.

Main advantages:
The joystick can rotate 360 ° horizontally, providing strong maneuverability.
The hand pump bracket supports inserting the handle from three positions, making the operator more user-friendly in terms of operating position and force application
The pump body piston can synchronously achieve hand pump self-locking, effectively protecting the plunger and ensuring higher safety
The operating space is greatly saved, and the operating handle is detachable, which reduces the installation space and packaging size. The advantage of the process pipeline layout with dense equipment installation is obvious
