Structural features

H44W / H stainless steel swing check valve automatically opens and closes by the force generated by the flow of the medium itself in the pipeline, which belongs to an automatic valve. The check valve is used in the pipeline system. Its main function is to prevent the medium from flowing backward, to prevent the pump and its driving motor from reversing, and to release the medium in the container. Auxiliary system on the supply line. Applicable to pipelines under various working conditions such as petroleum, chemical, pharmaceutical, fertilizer, and power industries with pressure PN1.6 ~ 16.0MPa and working temperature -29 ~ + 550 °. The applicable medium is water, oil, steam, acid medium, etc.
