This automatic control valve requires no external power or air supply, relying on the pressure of the controlled medium itself as the power source to achieve automatic adjustment and stable control of pressure or differential pressure in pipelines or systems.
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.
Self-operated pressure/differential pressure control valves are automatic control valves that do not require external power or air supply. They utilize the pressure of the controlled medium itself as the power source to achieve automatic adjustment and stable control of pressure or differential pressure in pipelines or systems.
These valves have a simple structure and reliable operation, and are widely used in heating, water supply, steam, and industrial pipeline systems.
