Description
The large-diameter CIL - Series 39F In-Line 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 through flow at minimum pressure drop across the valve at all times. Forward pressure opens the valve automatically and reverse pressure seals the valve. The check sleeve even seals around entrapped solids. This inner elastomer check valve minimizes wear and deterioration caused by continuous operation of abrasive slurries. There are no mechanical parts such as hinges, disks or metal seats that can freeze, corrode or bind valve operation.
The Series 39F In-Line Check Valve is provided with clean-out ports and flush ports for routine maintenance and cleaning. The valve features an epoxy-coated, fabricated-steel body. The valve has thru-drilled flange holes and face-to-face dimensions meet ASME B16.10 specs. The Series 39F is also available in a plain end x plain end configuration. The Series 39F can also be specially fabricated with offset flanges and a RTF-1 sleeve when bottom clearance is limited (consult factory for special configurations). When ordering, line pressure and back pressure must be provided, as each valve is custom-built to match the flow requirements of the installation.
