The ZZY series self-operated pressure regulating valve is a control valve that automatically regulates pressure using the pressure of the controlled medium itself, without requiring external power or air supply. It is primarily used for stable control of inlet pressure, outlet pressure, or system pressure in pipelines or equipment.
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.
