Pneumatic control valve

Pneumatic control valve uses compressed air as power source to automatically regulate flow rate, pressure, temperature and liquid level of liquid, gas, steam and other media.

It features fast response, safe performance and explosion‑proof property, widely applied in chemical, petroleum, power plant, metallurgy, pharmaceutical and heating industries.

It is the core component of industrial automatic control systems to keep process parameters stable.

Working Principle：
Compressed air drives the pneumatic actuator to move the valve plug up and down, changing the flow area. With valve positioner, it converts electric control signals into air pressure signals for continuous modulation.
