ZHYH46 / ZHYH46EJ Micro-resistance Slow-closing Butterfly Check Valve Structure

Scope of application

ZHYH46 / ZHYH46EJ micro-resistance slow-closing butterfly check valve can be used on the water supply and drainage pipes of water, sewage, seawater and other media, which can prevent the medium from flowing backward, and can effectively limit the destructive water hammer and ensure the safe use of the pipeline. The valve has a novel structure, small size, reliable sealing, stable opening and closing, wear resistance, long service life, slow oil pressure closing without being affected by the medium, small flow resistance, wide application range, and good energy saving effect.
