Gate Valve suppliers Overview The Pneumatic Actuated Gate Valve is a valve that is driven by compressed air. When the gate valve is closed, the sealing surface can rely solely on the pressure of the medium to seal. Most of the gate valves are forced to seal, that is, when the valve is closed, rely on external force to force the gate plate to the seat to ensure the sealing of the sealing surface. The Pneumatic Actuated Gate Valve is made of excellent metal and is finely polished and processed. The body of the Pneumatic Actuated Gate Valve has a refined appearance without any burrs. The Pneumatic Actuated Gate Valve is characterized by simple control, fast response and is intrinsically safe, requiring no additional explosion protection. It is usually a combination of a pneumatic actuator and a regulating valve, which are connected and commissioned to form an instrument. It has been one of the industrial process control instruments widely used in electric power, petroleum, metallurgy, chemical and other industrial enterprises.
