Wafer Tilting Disc Type Check Valve
H77 check valve is a flanged non-impact check valve with flange size of ASME B16.5 GB HG SH. Its main advantage is to overcome the impact and water hammer phenomenon caused by the rotary check valve and the lifting upreturn valve under the working condition, and to realize the non-impact operation.
Double eccentric disc, when closed, the valve contact with the sealing surface step by step, to achieve no impact, no noise work. Micro elastic metal seat, good sealing performance. Butterfly disc design, fast switch, sensitive, long service life. The oblique disk structure makes the fluid channel streamline, the flow resistance is small, and has the effect of energy saving.
