P ®® TECHNICAL BULLETIN <br /> TB010 <br /> Franklin Fueling Systems 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 T13011 for a thorough definition of AG). <br /> "R" or"W" Stamp Date Code ID Plate <br /> R 040,, (YYMM) <br /> If there is no stamp, <br /> then assume"Std". <br /> F <br /> t <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 /> Franklin Fueling Systems • 3760 Marsh Rd. • Madison, WI 53718 USA <br /> Tel: +1 608 838 8786• 800 225 9787 • Fax: +1 608 838 6433 •www.franklinfueling.com <br />
