The Val-Matic Surge Buster from HMA Flow & Industrial features a 100% flow area for improved flow characteristics and lower head loss. The unrestricted flow area, combined with smooth streamlined contouring, allows passage of large solids, minimising the potential for clogging. The one-piece precision-moulded disc is steel and nylon reinforced to provide years of trouble-free performance. It is backed by a 25-year warranty for the flex portion of the disc.
The Memory-Flex disc and the Disc Accelerator are the only moving parts. There are no packing, mechanical hinges, pivot pins or bearings to wear out. The hinge portion of the disc is guaranteed for 25 years. The synthetic reinforced disc, with its integral O-ring type seal design, assures positive seating at high and low pressures.
A full-size top-access port allows for removal of the disc without removing the valve from the line, and provides flushing action over the valve disc for clog-free performance. The access cover includes a drilled and tapped port for installation of an optional Disc Position Indicator. The Val-Matic Surge Buster from HMA Flow & Industrial is AWWA C508 certified, NSF/ANSI 61 certified for drinking water, and NSF/ANSI 372 certified lead-free.
