Installed within deluge, preaction, and special hazard systems, this differential diaphragm valve holds back water supply under normal conditions and instantly releases a high-volume flow upon system activation by hydraulic, pneumatic, or electric release controls. It is equally suited for fixed water-foam sprinkler setups deployed in high-hazard environments.\u003c\/p\u003e \u003cp\u003eThis valve assembly fulfills stringent life safety mandates outlined in NFPA 13 (Standard for the Installation of Sprinkler Systems) and related commercial fire protection codes. By providing reliable, rapid-response water delivery while minimizing pressure loss, it satisfies the strict performance criteria required by UL and FM for automated fire control infrastructure.\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eDuctile Iron Body:\u003c\/strong\u003e Crafted from high-grade ductile iron to withstand demanding physical loads in industrial facilities.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eDifferential Diaphragm Design:\u003c\/strong\u003e Utilizes a single moving mechanism for immediate, dependable flood valve actuation upon release.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eHigh-Pressure Operation:\u003c\/strong\u003e Rated for a maximum working water pressure of 250 PSI (17.4 bar) and factory tested up to 500 PSI (34.5 bar).\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eFlexible Mounting:\u003c\/strong\u003e Engineered for seamless installation in both horizontal and vertical pipeline orientations.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCorrosion Protection:\u003c\/strong\u003e Select models feature specialized internal and external Halar ECTFE coating for chemical, acid, solvent, and salt water resistance.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eSystem Versatility:\u003c\/strong\u003e Fully compatible with hydraulic, pneumatic, or electric release configurations and foam-water distribution.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ctable\u003e \u003cthead\u003e \u003ctr\u003e \u003cth\u003e\u003cb\u003eTechnical Parameter\u003c\/b\u003e\u003c\/th\u003e \u003cth\u003e\u003cb\u003eSpecification\u003c\/b\u003e\u003c\/th\u003e \u003c\/tr\u003e \u003c\/thead\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eManufacturer \/ Brand\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eViking\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eModel \/ Series Number \/ SIN\u003c\/strong\u003e\u003c\/td\u003e \u003ctd\u003eF-1 \/ F-2 Deluge Valve Series\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003e\u003cstrong\u003eConnection \/ Thread Size \u0026amp;
