Victaulic® FireLock® Check Valves


Grooved ends allow fast, easy installation with just two Victaulic couplings or the valve may be mounted to flanged (ANSI CL.150) equipment using either to Victaulic Style 741 Vic-Flange® or Style 744 FireLock flange adapters on either end.

The FireLock Series 717 Check Valve and Series 717H High Pressure Check Valves are CAD designed for hydrodynamic efficiency and available in 2"/50 mm – 3"/80 mm (Series 717H) and 2 ½"/65 mm – 12"/300 mm (Series 717) sizes. Series 717H valves are cULus Listed and FM Approved for service up to 365 psi/2517 kPa. See chart below for approved services for the Series 717 valves. In both valve designs, the single-disc mechanism incorporates a spring-assisted feature for nonslamming operation. This spring-assisted, single-disc design achieves a leak-free seal with as little as 5ft /1.5m of head. Series 717 and 717H FireLock Check Valves can be installed either vertically (flow upwards only) or horizontally. A cast flow arrow indicator is provided to assist with proper valve orientation. Both valves include upstream and downstream pressure taps. Each valve is factory-tested to the rated working pressure. For systems requiring a Riser Check option, refer to publication 10.09.
