What is COVNA Pneumatic Control Valve?

Pneumatic control valves are mainly used in transportation systems in medical, food, petroleum, natural gas, water treatment, and other industries, and are suitable for controlling gas, steam, liquid, and other media. Compared with other general pneumatic actuator valves, it adds some control components, and the whole is more complicated, so the required debugging process is naturally more complicated.

Today, we will talk to you about the COVNA pneumatic control valve.

It is characterized by simple control, fast response, intrinsic safety, no need to take additional explosion-proof measures and receives control signals from industrial automation control systems to adjust various process parameters such as flow and pressure of pipeline media.

Pneumatic control valve is usually composed of a pneumatic actuator and modulating valve connection, installation and debugging. Pneumatic actuators can be divided into two types: single-acting and double-acting. There is a return spring in the single-acting actuator, while there is no return spring in the double-acting actuator. Among them, the single-acting actuator can automatically return to the open or closed state initially set by the valve in the event of loss of origin or sudden failure.

The pneumatic control valve is divided into two types: air-opening and air-closing according to the active form, the so-called normally open type and normally closed type. The air-opening or air-closing of the pneumatic control valve is usually through the positive and negative action of the actuator and the valve state structure of different assembly methods.

What Is The Function Of The Pneumatic Control Valve?

It can be used to adjust the flow rate and pressure of the valve medium, convert the air pressure into motion and use the air as the control medium to open, close or adjust the flow rate as required by the pneumatic actuator.
