vPW 1 0 RVEME RGE FICYT-OFF VALVES <br />OPW TORP Series <br />OPW IORP valves have the same features as the traditional IOR emergency shut- <br />off valves, but in addition, offer a secondary poppet to limit spillage from the dis- <br />penser after a knock -down or during installation. <br />I <br />7 <br />Materials <br />8 <br />Top: cast iron* <br />Body: cast iron* <br />Disc: M-19 <br />Carrier: plated steel <br />Stem: copper -nickel -chrome plated brass <br />Poppet spring: stainless steel <br />Seal: M-19 o -ring <br />Packing nut: brass, Teflon® coated I.D. <br />Inlet and outlet thread: I %" NPT <br />*with Black Duragard® coating <br />Dimensions <br />IORF IORFP <br />IORM <br />IORMP <br />IORU <br />IORUP <br />IORFS IORFSP <br />IORMS <br />IORMSP <br />IORUS <br />IORUSP <br />IORFC IORFCP <br />IORMC <br />IORMCP <br />IORUC <br />IORUCP <br />IORFSC IORFSCP <br />IORMSC <br />IORMSCP <br />IORUSC <br />IORUSCP <br />in. mm. in. mm. <br />in. mm. <br />in. mm. <br />in. mm. <br />in. mm. <br />A 1 %6" 46 1'16' 46 <br />1%6" 46 <br />1 %6" 46 <br />1'M6' 46 <br />1'%6' 46 <br />- B 6'/+" 159 6%" 165 <br />04" 169 <br />N" 194 <br />7'/6' 183 <br />7%" 187 <br />C 2Y4" 70 214" 70 <br />2Y" 70 <br />2K' 70 <br />214" 70 <br />214" 70 <br />D 02" 115 032 115 <br />02" 115 <br />02" 115 <br />4"/n" 115 <br />4"/2" 115 <br />E 1%' 44 2/6 52 <br />2/<" 57 <br />3/< 83 <br />2/ <br />1.

Thermal Relief Valve — to reduce <br />pressure build up due to thermal <br />expansion. <br />3. Secondary poppet in open position <br />by pumping pressure. <br />4. Secondary poppet normally in <br />closed position. <br />5. When properly installed, all IOR <br />and IORP valves break at the shear <br />groove causing the valve to close <br />and preventing further gasoline <br />spillage. <br />6. Main poppet normally held open by <br />linkage. <br />7. Main poppet in closed position. <br />8. Inlet available with or without <br />threads for use with double <br />containment. <br />SUL NI <br />
