TeeJet® ChemSaver® Diaphragm Check Valves

September 2nd, 2009

Teejet Chemsaver Diaphragm
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
