  • Introduction
  • Technical Parameters

H44H, H44Y type PN16~PN250 Swing Check Valves are applicable to pipelines in various working conditions such as petroleum, chemical, pharmaceutical, chemical fertilizer, power industry, etc. with operating pressures of from 1.6 to 25MPa and operating temperatures from -29 to +550°C. Water, oil, steam, acidic media, etc.

H44H, H44Y Swing type check valve is automatically opened and closed by the force generated by the flow of medium in the pipeline itself, belonging to an automatic valve. The check valve is used in the piping system. Its main function is to prevent the back flow of the medium, prevent the pump and its drive motor from reversing, and release the medium in the container. Check valves can also be used on pipelines where the pressure may rise above the main system's auxiliary system.
