MWP releases new hydrant, expands valve product line

Mueller Water Products, Inc. has announced it is launching the Super Centurion A-403 Fire Hydrant, designed to be installed and maintained by one person. In addition, Mueller is expanding its 250/300 Resilient Wedge Gate Valve product line with a new end design.

Super Centurion A-403 Fire Hydrant features a two-piece ductile iron upper barrel with a nozzle section that can be separated from the traffic section by removing two high strength bolts, making seat replacement or traffic repair simple and quick. The A-403 has a traffic flange, 5-1/4” fully encapsulated, reversible main valve, a durable polyurethane top coat and automatic oil lubrication. In addition, all internal components, nozzles and repair parts are fully interchangeable with the Super Centurion 250 hydrant.

Initially, the A-403 is available with a 5-1/4″ main valve and a 3-way opening configuration (2 hose nozzles / 1 pumper nozzle).   This lightweight dry barrel fire hydrant is certified UL/FM/AWWA at 350psi operating pressure and factory tested to 700psi.

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 (end-to-end) 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 in., 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 & yoke (OS&Y) configurations, in both Mueller and U.S. Pipe Valve & Hydrant brands.
