Rubber Flapper Swing Check


Unique Simple Design. The Flapper does not swing from a Hinge Pin, it flexes open. The seat is on a 45 degree angle. The Flapper travels 35 degrees from open to close, very fast, and before column reversal can occur, hence, it's non-slamming. The flapper is made of synthetic rubber. The spring accelerates the valve closure. The valve can be buried and requires no regular maintenance. Recommended for Water, Sewage, Gas, Oil and Rubber lined for Chemicals. Ductile Iron, Fully Adjustable Body rated 125# class 175 PSI working pressure.

Higher Pressure Available.
