751 2 Check Valve

Victaulic Series 751 (2″) is a FireLock™ alarm check valve used in wet fire sprinkler systems to prevent the reverse flow of water from the system piping back into the water supply while simultaneously providing alarm activation when water flows due to sprinkler discharge; it features 2″ grooved inlet and outlet connections (typically 2.375″ OD), a ductile iron body, and is UL Listed and FM Approved with a 300 psi working pressure, making it suitable for NFPA-compliant commercial and industrial fire protection installations where compact, reliable alarm check functionality is required.
