Pneumatic control valves use compressed air as the power source and receive control signals (typically 4–20mA) through a valve positioner to precisely control the valve stem travel or rotation angle, achieving continuous automatic regulation of the flow rate, pressure, level, or temperature of the medium in the pipeline.
Our control valves are engineered with optimized flow paths and control trims to deliver accurate, repeatable control across a wide operating range.
Specialized designs are available for high pressure, high temperature, corrosive, abrasive, and high differential pressure applications.
We offer a wide selection of valve body and trim materials, carefully selected to match process media and service conditions.operation.
Pneumatic control valves use compressed air as the power source and receive control signals (typically 4–20mA) through a valve positioner to precisely control the valve stem travel or rotation angle, achieving continuous automatic regulation of the flow rate, pressure, level, or temperature of the medium in the pipeline. Due to their fast response speed, stable operation, and high safety, these valves are widely used in industrial process control systems.
