Product Usage

H44H, H44Y type PN16~PN250 swing-type check valve is suitable for pipelines of various working conditions such as petroleum, chemical, pharmaceutical, fertilizer and electric power industries with pressure of 1.6~25MPa working temperature -29~+550°C. Water, oil, steam, acidic medium, etc.


Features

H44H, H44Y type swing check valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, and belongs to an automatic valve. The check valve is used in the piping system and its main function is to prevent backflow of the medium, prevent the pump and its drive motor from reversing, and discharge the medium in the container. The check valve can also be used to supply a supply line to an auxiliary system where the pressure may rise above the main system pressure.
