The Tideflex Technologies 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 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 39 In-Line 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"
