Installed in main water supply lines, this assembly utilizes precision-molded thermoplastic checks and an N pattern layout to prevent backflow and maintain steady water delivery under fluctuating pressure conditions. The integrated outside screw and yoke (OS&Y) gate valves feature a rising cast iron stem that lets you visually confirm valve position instantly during routine maintenance.
This assembly satisfies strict regulatory demands by meeting ASSE 1013 standards and supporting NFPA 13 and NFPA 25 requirements for fire protection system installation and periodic testing. It carries formal agency recognition, including UL Listing to UL 262 and FM Approval, ensuring code compliance for commercial contractors and facility managers.
