Tideflex ® Technologies’ Series 37 Flanged InLine Check Valve is a simple, reliable, cost-effective solution to backflow prob- lems. Designed to be installed between twomating flanges, the Series 37 eliminates the need for a valve body. With only one moving part, the maintenance-free rubber check sleeve, the Series 37 InLine Check Valve is simple in design. Sliding, rotating, swinging and spring parts are eliminated. There are no seats to corrode or packing to maintain. In addition, the Series 37 is a passive design, requiring no external source of air or elec- tricity to operate. The result is reduced operating costs. The Series 37 InLine Check Valve can be ordered in a variety of elastomers. Flanges conform to ANSI B16.1 Class 125 specifi- cations. Special custom designs or metric flanged models are also available. When ordering, specify line pressure, backpres- sure and whether an SST is required. Max.
