The expansion of Mueller’s 350psi, AWWA/UL/FM rated resilient wedge gate valve (RWGV) product line with new end design conforms to the ASME/ANSI dimensional requirements for Class 250/300 valves. Specifically, the flange and lay length of the new Class 250/300 RWGV complies with ASME/ANSI B16.1, B16.42, B16.10, and PN25 drilling standards. This ductile iron valve is available in standard sizes from 3 to 12 inches, complies with the requirements of AWWA C509/C515 and NSF 61/372, and retains all competitive features of other 350psi rated RWGVs including integrated lift lugs, a self-activating wedge seal and grade 316 stainless steel fasteners.
Typical applications include mechanical rooms of high-rise buildings, pump stations, reservoirs, and water processing facilities that operate at higher pressures. Class 250/300 RWGVs are available in non-rising stem (NRS), post indicating (PI), and outside screw and yoke (OS&Y) configurations, in both Mueller® and U.S. Pipe Valve & Hydrant® brands.
