YZH Series Pneumatic Linear Actuator

Description of Pneumatic Linear Actuator

The YZH series pneumatic linear actuator uses 0.4~0.6MPa (gauge pressure) purified compressed air as the working power to push the piston and drive the valve gate to make linear motion perpendicular to the fluid to achieve the purpose of adjusting, opening, and closing the valve. YZH series actuators are suitable for most wedge gate valves, flat gate valves, knife gate valves, globe valves, discharge valves, orbital ball valves, orbital plug valves, etc.

The YZH Series straight-stroke pneumatic actuators are manufactured strictly by quality standards to ensure reliability and safety. This sample lists standard models of products, aiming to cover a wide range of application series, and can be designed and manufactured according to user needs.

Benefits Of Pneumatic Linear Actuator

The integrated mounting plate does not require traditional mounting brackets, thus reducing the number of components that need to be installed.

The manual mechanism adopts worm gear, screw drive, and other designs.

The pneumatic actuator has a lubrication system, which can provide very smooth valve control.

The sealing ring and guide ring ensure that even if the cylinder piston rod is acted upon by a directional force, there will be no direct friction between the piston and the metal surface of the cylinder’s inner wall.

Stroke limits and manual devices can be used in almost any control valve application.

Sturdy and durable thick-walled cast iron and cast steel structures provide better stability and corrosion resistance
