PNEUMATIC CONTROL VALVE POSITIONER
OVERVIEW
Pneumatic control valves are widely used in industrial automation control systems to adjust process parameters such as medium flow, pressure, temperature, liquid level, etc. It is mainly composed of pneumatic actuators and adjustment mechanisms, and uses compressed air as a power source to achieve precise control of the valve.
FEATURES
Simple control
The pneumatic control valve controls the movement of the piston or diaphragm through air pressure, thereby adjusting the opening of the valve disc to control parameters such as medium flow, pressure, and temperature. This control method is relatively simple and easy to operate and maintain.
Intrinsically safe
Since the pneumatic control valve uses compressed air as its power source, no additional explosion-proof measures are required, which makes it more secure.
Quick response
The pneumatic control valve has a fast response speed and can quickly adjust the flow, pressure and other parameters of the medium according to the control signal to ensure the stability and reliability of the production process.

APPLICATIONS
Energy system
Oil/gas pipelines: used for medium flow switching and multi-branch flow distribution, replacing the traditional multi-valve complex system;
Power generation: control the flow direction of thermal/nuclear power steam, and adjust the circulating water path of boilers and cooling systems.
Industrial control
Chemical reaction system: realize the diversion and mixing of corrosive media such as acids and alkalis, and match the corrosion resistance requirements of PTFE/PPL sealing materials;
Metallurgical equipment: cooling water forward and reverse switching, high temperature scene adaptation metal seal (temperature resistance ≤450C).
Urban infrastructure
Water supply and drainage network: quickly switch the forward and reverse water supply direction to meet the needs of emergency conditions;
Heating system: adjust the flow direction of steam/hot water, adapt to flange or welding connection methods
