Drip-Free Diaphragm Check Valve

1/4" MPT x 1/4" FPT, Viton® Seal, 25 PSI

Designed to deliver the highest flow rates across the spray pressure range, these 1/4" drip-free diaphragm check valves are the perfect choice for applications featuring chemical or soap arches. The nozzle body is made from quality nylon for excellent corrosion, impact, and temperature resistance for a long-performing life of the check valve. The single drop threaded nozzle bodies for wet booms have a 1/4" MPT inlet by 1/4" FPT outlet and are designed for 1/4" spray nozzles to screw directly in with ease. The diaphragm check valves are rated to a maximum 300 PSI and are capable of 3 GPM. A Viton® O-ring ensures absolute leak-proof operation.
