The unique design of rubber flapper disc with the hi-strength fabric reinforced which creates an elastic spring effort to close-against the flow, combined with the tilted body seat act to reduce the closing time, minimize the water hammer and flow reversal.
The simplicity in design, three components (Body, Flapper & Cover) in one valve, and disc, hinge & pin are integral in one piece with fully special rubber encapsulated offer for maintenance free, 1,000,00 continuous cycles tested with no sign of wear or distortion to the valve disc and seat.
