Dual Diaphragm Check Valve (DDCV)
Dual Diaphragm Check Valve (DDCV)
Dual’s Diaphragm Check Valve is drip-proof and may be mounted in any position. As there are no moving metal parts, operation is silent. For superior shock resistance, glow plates are Carbon Steel which can be coated for various applications. If required, valves can be manufactured in Stainless Steel. The incorporation of a natural rubber disc results in positive closure, the elimination of water hammer and negligible maintenance. The rubber disc does not stretch on opening, eliminating tearing. Diameter and port design of the flow plate allows for easy flow.
