Hale Products Inc.`s FOUR-INCH FULL-FLOW BRASS BALL VALVE is designed to work with Hale`s new Muscle pumps–the Qflo, Qmax, and Qtwo. Engineered to exceed NFPA requirements, the MaxFlo valve has options for either power or manual controls. The Maxflow offers several interchangeable-end options–four-inch x eight-bolt, 312-inch x four-bolt, Victaulic, NPT, or NST for mounting flexibility. V-clamp connections make assembly to the Hale midship a breeze. The Maxflo is the shortest four-inch valve available. Designed for easy installation and maintenance, V-clamp connections allow the valve to rotate 360 degrees, and the dropout feature eases servicing.
