Request a QuoteProduct Overview
WUYI's high-pressure grease-injection control valves are suitable for a wide range of fluids under varying pressures and temperatures. With a compact body and streamlined S-type flow path, they offer low pressure loss, high flow capacity, wide control range, and precise flow characteristics. The balanced plug design ensures stable performance, low noise, minimal vibration, and reduced sensitivity to temperature—ideal for high-flow, high-temperature applications with moderate leakage requirements.
Key Features
WUYI's plug offers a wide range of Cv values, and the seat sealing performance meets international control valve standards. The valve is equipped with pneumatic or electric actuators, featuring a compact structure and high output force, making it ideal for high-temperature applications requiring high reliability and tight shut-off. The addition of a sealing grease injection system and dual-seal design significantly enhances stem packing life and sealing performance under steam and high-temperature conditions.
