FE PETRO" TECHNILAL BULLETIN <br /> j Systems T13010Franklin Fueling Y February 6,2009 <br /> Check Valve Models <br /> The check valves produced by FE Petro were developed to accommodate a variety of electronic and mechanical <br /> equipment used in Line Leak Detection today.Electronic Line Leak Detectors manufactured by several companies require <br /> that the line pressure relieve to a certain pressure(in PSI)to conduct a proper leak test.This relief pressure varies <br /> depending on the requirements of the electronic equipment. <br /> FE Petro's Check Valve Models <br /> Model"STD"Part Number 400988931 , <br /> • Opens at about 40 PSI(2.8 bar). <br /> • Resets above 35 PSI(2.4 bar). <br /> • Typically used for Mechanical Line Leak Detectors(MLD)and some electronic line leak detectors(i.e.,Incon,Emco /• <br /> Wheaton,and RJ ST). <br /> • Identified with Silver ID Nut. <br /> Model"R•'Part Number 400988932 <br /> • Opens at about 24 PSI(1.7 bar). <br /> • Resets at about 22 PSI(1.5 bar). <br /> • Typically used for Veeder Root Electric Line Leak Detectors(PLLD). <br /> • Identified with Black ID Nut and"R"stamped on top of washer. <br /> Model"W"Part Number 400988933 <br /> • Opens at about 16 PSI(1.1 bar). <br /> • Resets at about 13 PSI(0.9 bar). <br /> • Typically used for Electronic Line Leak Detectors Systems that require low reset pressures. <br /> • Identified with Silver ID Nut and W"stamped on top of washer. <br /> Model"65 PSI"Part Number 402459931 (new in October 2001) <br /> • Opens at about 70 PSI(4.8 bar). <br /> • Resets at about 65 PSI(4.5 bar). <br /> • For use on Secondary pumps in manifolded systems only,where applicable. <br /> • Sold as a replacement part only,not factory installed. <br /> Note: When ordering FE Petro STP/ISTs,the STD model check valve is implied unless specified otherwise. Always <br /> consult with Line Leak Detector manufacturers before choosing a check valve. All FE Petro check valve models <br /> are AG compatible(see Technical Bulletin TB011 for a thorough definition of AG). <br /> "R"or"W"Stamp Date Code ID Plate <br /> a 040 (YYMM) <br /> If there is no stamp, <br /> then assume"Std". <br /> ID Nut <br /> Top View of Check Valve Top View of"65 PSI Check Valve <br /> ("R"shown) <br /> ID Nut:Silver="Std"or"W',Black="R" <br />
