1'SHUT-OFF <br />0 <br />Top Connection Styles <br />There are three types of top or outlet <br />connections available: <br />♦ "U" designates 1%" union connec- <br />tion. <br />♦ "F" designates 1%" internally <br />threaded top. <br />♦ "M" designates 1%" externally <br />threaded top. <br />Single or Double Poppets <br />Traditional OPW 10 Series <br />Emergency Shut-off Valves feature <br />a single poppet. The IOBP Series <br />features double poppets and is <br />designed to help contain product <br />within the dispenser. <br />Suction Capabilities <br />Double poppet models are also avail- <br />able for suction system applications <br />(where the secondary poppet is in the <br />0losed position until the suction pump <br />is engaged, in order to hold the prime in <br />the line) by ordering the OPW IOSBP. <br />Containment Options <br />Externally threaded valves for double <br />containment applications are available. <br />vim■ <br />OPW 1OBP Series <br />OPW IOBP Series Valves have the same features as the single poppet emergency <br />shut-off valves, but include the added benefits of a secondary poppet to limit spillage <br />from the dispenser if a separation of the top and body should occur at the shear <br />groove. <br />1. Outlet — Available with an internal- <br />ly threaded, externally threaded or <br />union connection. <br />2. Thermal Relief Valve — to reduce <br />pressure build up due to thermal <br />expansion. <br />3. Secondary poppet limits spillage <br />from the dispenser. <br />4. Hold -open bridge allows the fuel to <br />flow more quickly and efficiently <br />during normal operation. <br />5. When properly installed, all OPW <br />10 Series single and double poppet <br />valves are designed to break at the <br />shear groove, in the event that the <br />pedestal is dislocated or overturned, <br />allowing the valve to close to help <br />prevent further gasoline spillage. <br />6. Main poppet is out of flow path. <br />7. Combination body offers the choice <br />of two built-in mounting options. <br />I <br />B <br />Dimensions <br />IOBF IOBFP IOBM IOBHMP IOBU IOBUP <br />10BFC 10BFCP 10BMC IOBHMCP IOBUC IOBUCP <br />l OSBFP I OSBHMP lOSBUP <br />IOSBFCP I OSBMHCP IOSBUCP <br />in. mm. in. mm. in. mm. in. mm. in. mm. in. mm. <br />A 21/2" <br />64 <br />21/2" <br />64 <br />21/2 <br />ribs <br />/2. <br />04 <br />21/2 04 <br />'11/2 <br />®` <br />B 621/64" <br />161 <br />621/64" <br />161. <br />613/16" 173 <br />711/16' <br />n <br />71/4" 184 <br />71/4' <br />184 <br />C 211/16' <br />69 <br />211/16' <br />; 69, <br />211/16" 6 <br />211/16" :7'69, <br />211/16" "69 <br />211/16" <br />69 <br />D 23/4 <br />70 <br />23/4" <br />70= <br />23/4"0 <br />23/4" <br />M' <br />23/4" `70 <br />23/4, <br />70 <br />E 13/4" <br />44 <br />13/4" <br /># <br />21/4" <br />... <br />31/8' <br />: <br />2t1/16" i6a <br />211/16 <br />X68 <br />9 <br />
