H44H-25C Check Valve
Introduction:
The H44H-25C check valve is suitable for pipelines in various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries, where the pressure ranges from 1.6 to 25 MPa and the working temperature ranges from -29 to 550 °C. The applicable media include water, oil, steam, acidic media, etc.
【Product Features】
The H44H and H44Y type swing check valves made of steel are automatically opened and closed by the force generated by the flow of the medium in the pipeline itself, belonging to a type of automatic valve. When check valves are used in pipeline systems, their main functions are to prevent medium backflow, prevent the reverse rotation of pumps and their driving motors, and the discharge of medium in containers. Check valves can also be used in pipelines that supply auxiliary systems where the pressure may rise above the main system pressure.
