FEBCO has announced its MicroSeries backflow preventer, featuring a "No Gates" design that is shorter and lighter than standard units. Integral butterfly valves serve as shut-offs, eliminating the need for heavy gate valves. The MicroSeries features a shorter lay length than traditional in-line backflow preventers. The 4" Model 830 double check has a flange-to-flange lay length dimension of only 22 inches, and it is 55% lighter than traditional in-line double checks with OS&Y gates. Available in 4" double check and double check detector, the line features sizes from 2 1/2" through 8". They also feature a choice in actuation of gear operator and tamper switch or manual lever handle. FEBCO. www.FEBCOonline.com
