Snap Check Valves

Spring-loaded "snap" check valve replaces filter element on fuel nozzle. Valve opens when fuel pump pressure reaches 130 PSI and "snaps" shut when fuel pressure drops below 130 PSI. Stops "smokey" burners at start-up and eleminates "shutdown" after burn and reduces soot build-up in coil.
Reduces nozzle fouling caused by residual fuel in orifice
Easy field installation in standard fuel nozzles
