Red Valve Company, Inc.x Series 39F is one of the larger inline check valves available, with sizes ranging up to 84-in. It is great for lift stations and flood control installations where debris such as tree branches and plastic bags will render flapper-style check valves inoperative. A newly patented curved-bill design provides a tight seal with little or no backpressure, and allows greater sealing around entrapped debris.
This elastomer "duckbill" check valve is corrosion-proof, operating under extreme conditions long after metal check valves have rusted open or frozen shut. It is also very cost-effective due to its low headloss characteristics, long service life and because it eliminates the need for routine lubrication or adjustment.
