New Six Inch Model G-6000 Dry and Preaction Systems

Wednesday, October 19, 2011

Hastings, MI, USA – Viking Corporation, a global leader in fire protection and life safety systems, has extended its innovative Model G valve line to now include up to a six inch size. The patent-pending Model G valves, which are also sold in two, three, and four inch sizes, offer many design and installation advantages including simplified trim, reduced weight, and a compact size. The new valves have a pressure rating of 250 PSI (17,2 bar) and feature a strong, lightweight, ductile iron body with black e-coat on both the inside and outside of the valve body for improved corrosion resistance.

Viking’s Model G valves are available in four system configurations; dry pipe, single interlock preaction, double interlock preaction, and Viking’s exclusive Surefire® fail-safe preaction system. Like all Model G systems, the G-6000 is shipped fully pre-assembled from the factory, including the G-6000 valve and complete trim package assembled to the valve. The water supply control valve, gauges, switches, drain cup, and drain connection are also included. Additionally, a grooved section of galvanized piping is installed on top of the Model G valve to facilitate installation and service.

In a dry system configuration, the Model G valves include an innovative external reset feature. To reset the valve, the installer simply re-establishes air pressure to the system and then pressurizes the valve’s unique priming chamber. In a fire condition, system air pressure is lost and the priming chamber compresses allowing water to pass through the valve and into the sprinkler system piping. All Model G valves also include an internal check valve, thus eliminating the need for a separate check valve in the system riser when installed as a preaction system.
