Check Valves and Backflow Preventers

Raptor Supplies offers an extensive range of check valves, backflow preventers (along with their accessories) & vacuum breakers from brands like Apollo, Dixon, Milwaukee Valve, Plast-o-Matic, SMC Valves, Watts and Wilkins. The flow check valves come with square-cut O-ring seats for proper sealing and providing minimum backpressure. Check and foot valves allow unidirectional flow and are widely used in sump / wet pumps for drawing water out of the well while restricting back siphonage. To prevent backflow because of vacuum generation in water drainage systems, vacuum breakers are ideal choice; available in brass, bronze, chrome-plated brass, lead-free bronze, lead-free brass and polished chrome material variants. We also have flow control valves used for regulating the fluid pressure and providing a positive shutoff in hydronic heating systems, boilers, indirect water heaters and chemical processing systems.
