H44H/Y type swing type steel check valve
【Product use】
H44H, H44Y type PN16~PN250 swing steel check valve is suitable for pipelines with various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and electric power industries with a pressure of 1.6~25MPa and an operating temperature of -29~+550℃. The applicable media is water, oil, steam, acidic media, etc.
【Product features】
The H44H and H44Y swing-type steel check valves are automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, and belong to an automatic valve.The check valve is used in the pipeline system. Its main function is to prevent the backflow of media, prevent the pump and its drive motor from reversing, and the discharge of media in the container.Check valves can also be used to supply pipelines to auxiliary systems where the pressure may rise to exceed the pressure of the main system.
