In some applications and installations, a slip-over pipe check valve (TF-1) is not feasible because of an existing flange in the piping system or an existing flange cemented in the outfall piping system vault. In these cases, the Series 35-1 Check Valve is the solution.
Series 35-1 Check Valves are manufactured identically to the Tideflexª TF-1 Check Valve, with the addition of an integral elastomer flange as part of the valve. The flange size drilling conforms to ANSI B16.10, Class 150#. It is also available with DIN, 2632, and other standards. All Series 35-1 Check Valves are furnished complete with steel back-up rings for installation
The Series 35-1 Check Valve is simple in design, with only one part – the all- rubber duck bill check sleeve. There are no seats or interference fits to corrode or freeze valve operation, making the Series 35 virtually maintenance free. The Series 35 can seal around small solids, making it ideal for fly ash, raw sewage, sludge, lime, mining slurries, and many other aversive and corrosive slurries. For higher backpressure ratings or to lower headloss while maintaining backpressure ratings, the SST can be used in conjunction with the Series 35
