Rubber Flapper Swing Check Valves feature a unique, simple design with only one moving part.
The flapper does not swing from a hinge pin; it simply flexes open.
The seat is on a 45° angle.
The flapper travels 35° from open to closed, usually before column reversal can occur.
It has non-slam characteristics.
The valve requires no regular maintenance.
Recommended for water, sewage, gas, oil and rubber lined for chemicals.
