F"p�® "�ECHNICAL BULLETIN <br /> ��GG T6010 <br /> Franklin Fueling Systems May 20, 2004 <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 <br /> require that the line pressure relieve to a certain pressure (in PSI) to conduct a proper leak test. This relief pressure <br /> varies depending on the requirements of the electronic equipment. <br /> FE Petro's Check Valve Models <br /> _ Model "STD" Part Number 40098893 <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., <br /> Incon, Emco 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" slam ed on to 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 STPIISTs, 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 <br /> models are AG compatible (see Technical Bulletin TB011 for a thorough definition of AG). <br /> " R 040?
