The Series 39 Slurry Check Valve is designed to handle abrasive slurries, sewage, sludge and other difficult services. At the heart of the Series 39 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 duckbill check valve minimizes wear and deterioration caused by continuous operation of abrasive slurries. And there are no mechanical parts such as hinges, disks or metal seats that can freeze, corrode or bind valve operation. The Series 39 Inline Check Valve, provided with a clean-out port and two flush ports, has a cast iron 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. For higher backpressure ratings or to lower headloss while maintaining backpressure ratings, the SST can be used in conjunction with the Series 39.
For smaller diameter applications, consider our threaded Series 2633 in sizes 1/2″-3″. For larger applications, consider the Series 39F Large Diameter Inline Check Valve in sizes to 84″.
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 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. And there are no mechanical parts such as hinges, disks or metal seats that can freeze, corrode or bind valve operation.
The Series 39F Inline Check Valve is provided with a 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 ANSI 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.
