In this type of nozzle body, the diaphragm check valve is an integral part of the nozzle assembly. This design eliminates the pressure drop associated with ball-type check valves. This spring-backed diaphragm ensures dependable closure. Originally developed for use in aerial spraying, nozzle bodies of this design are now widely used whenever drip-free shutoff is required. For maximum operating pressures of 125 psi (9 bar).

Typical Assembly

End cap subassembly
Valve seat
Strainer
Orifice disc and core
