Series 717R FireLock check valves are approved for vertical or horizontal installation and designed to accept a
riser check kit. The kit consists of a 2" (50 mm) drain valve, O - 300 PSI (0 - 2065 kPa) gauges (2), gauge isolation
valves (2), pipe nipples and pipe plugs. The Series 717R does not include the riser check kit. unless specified.
A welded-in nickel seat provides extra corrosion protection and leak-free sealing under as low as five (5) feet of
head. The basic valve is factory tested and is UL/ ULC Listed and FM Approved.

| NOTE: Placement of check valves too close to sources of unstable flow will shorten the life of the valve and potentially may damage the system. To extend valve life valves should be installed a reasonable distance away from pumps, elbows, expanders, reducers or other similar devices. Sound piping practices dictate a minimum of five (5)times the pipe diameter for general use. Distances between three (3) and five (5) diameters are allowable provided the flow velocity is less than eight (8) feet per second (2.4 mps). Distances less than three (3) diameters are not recommended. |
