Description

Vatac Series Duckbill Check Valves are a flexible sleeve design made of quality fab- ric-reinforced elastomer materials for maxi-mum resistance to corrosion and wear caused by continuous operation with abrasive slurries, sludge, or effluent. The flexible sleeve provides maximum flow with a mini-mum pressure drop across the valve at all times. The "duckbill" concept check valve has been in use for over 100 years in waterworks and commonly accepted for use in industrial process piping systems and in waste and storm water or sewer piping systems.

The simple, one-piece "duckbill" sleeve elimi-nates moving components and intrusive body structures that create problems with conven-tional check valve designs. There are no mechanical parts that can freeze, corrode, bind, or otherwise inhibit smooth operation. Unlike conventional check and flap gate valves, the Cla-Val Duckbill Check valve does not require regular maintenance to replace worn seats, hinge pins, balls, or flappers.

Vatac Flange Duckbill Check Valves feature an integral, metal-backed, rubber flange for attaching directly to flanged-end connections from tank or head wall. A variety of elastomers allow DBF valves to be used with many different fluids.
