Pneumatic regulating valves are powered by compressed air, using cylinders as actuators, and driven by accessories such as valve positioners, converters, solenoid valves, holding valves, air tanks, and gas filters to control the valve for on/off or proportional adjustments. They receive control signals from industrial automation control systems to regulate various process parameters of the pipeline medium, including flow rate, pressure, temperature, and liquid level. The characteristics of pneumatic regulating valves are simple control, rapid response, and inherent safety, eliminating the need for additional explosion-proof measures.
