The Series 39F Large-Diameter Slurry Check Valve is designed to handle abrasive slurries, sewage, sludge and other difficult services. The valve’s operation is silent and non-slamming, just like the smaller Series 39.
At the heart of the Series 39F Check Valve is a fabric-reinforced elastomer check sleeve that provides thru-flow at minimum pressure drop across the valve at all times. Forward pressure opens the valve automatically; reverse pressure seals the valve. The check sleeve even seals around entrapped solids.
This inner rubber check valve minimizes wear and deterioration caused by continuous operation of abrasive slurries. And there are no mechanical parts such as hinges, discs or metal seats that can freeze, corrode or bind valve operation.
The Series 39F In-Line Check Valve is provided with a clean-out ports and flush ports for routine maintenance and cleaning. The valve features a fabricated-steel body, which is available epoxy-coated or rubber-lined. The valve has thru-drilled flange holes; face-to-face dimensions meet ANSI B16.10 specs. When ordering, line pressure and back pressure must be provided as each valve is custom-built to match the flow requirements of the installation.
The Series 39F is available in sizes up to 84".
