Pneumatic diaphragm high-temperature control valves have a mature structure and stable operation, featuring high temperature resistance, sensitive response, and high control accuracy. They are widely used in high-temperature steam, heat transfer oil, and high-temperature gas 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.
Pneumatic diaphragm high-temperature control valves utilize a pneumatic diaphragm actuator as the power source and are specifically designed for continuous and precise regulation of medium flow, pressure, temperature, or liquid level under high-temperature conditions. These valves have a mature structure, stable operation, and feature excellent high-temperature resistance, sensitive response, and high control accuracy. They are widely used in high-temperature steam, heat transfer oil, and high-temperature gas systems.
