n <br />t�J <br />C <br />OPW 10RW Wrench is available <br />for easy valve installation. For <br />use with all 10 series valves <br />except the 10BHMP. <br />CAUTION: Do not attempt to tighten valve onto <br />riser by wrenching above the shear section. If <br />you do, the shear section will break. <br />Figure;j <br />HOW TO ATTACH OUTLET OF VALVE TO <br />DISPENSER PIPING <br />OPW 10 Series Intemal and External Tops <br />Hold valve steady with one wrench on hex <br />surface "F" — if wrench is turned, shear section will <br />break. The second wrench is used to tighten the pipe <br />being attached. <br />OPW 10 Series Union Tops <br />Hold valve steady with one wrench on hex <br />surface "F" just above shear section — if wrench is <br />turned, shear section will break. The second wrench <br />is used to tighten the union ring "G". <br />REQUIRED MAINTENANCE <br />The service application of this valve requires that <br />it do nothing until it is needed in the event of an <br />emergency. Therefore, to provide for proper action in <br />event of an emergency, the following procedure is <br />required: At least once each year, manually open <br />and loosen the valve several times to help prevent <br />gum deposit build-up and/or other conditions that <br />may affect the operation of the valve. <br />WARNING: Anytime an OPW 10 Series Emergency <br />Valve is being tested or serviced, the power to the <br />pumping system must be tamed off. <br />OPW 10 Series Emergency Shut -Off Valves <br />HOW TO OPEN VALVE MANUALLY <br />After the valve has been attached to riser and <br />pedestal piping, and pressure testing completed it <br />should be cocked open. To open the valve, rotate the <br />hub sub -assembly to the left (counter -clockwise), <br />raise the hub sub -assembly link and engage it with <br />the pin in the hub sub -assembly. (See Figure 4.) <br />HOW TO SHUT OFF VALVE MANUALLY <br />These valves may be closed manually by either <br />of two methods: <br />1. By pushing down on the hub sub -assembly <br />link. (See Figure 4.) <br />2. By first moving the hub sub -assembly slightly <br />to the left (counter -clockwise), then to the <br />right (clockwise). <br />PRESSURE TESTING THE PIPING SYSTEM <br />Note: This testing is for piping system only. <br />The tank should be isolated and not subjected to the <br />pressure used in testing the piping system. (See <br />NFPA Code 30A for tank test recommendations:) <br />After isolating tank, test piping as follows: Each <br />OPW 10 Series Emergency Valve has a built in 3/8" <br />test plug to permit testing of the piping system for <br />leaks after installation. To use this valve in testing the <br />piping, be certain pump is tumed off, then close the <br />valve manually, remove test plug, and attach test line <br />as shown. There is no need to break the line above <br />or below the valve or to remove valve. <br />NOTE: To prevent damage to the valve seat and disc, <br />DO NOT apply more than 50 -psi pressure to the test <br />line. See NFPA 30A for test details. A separate test <br />is required for the tank. <br />CAUTION: Do not use Teflon tape on threads. Coat <br />test line or test plug threads with small amount of a <br />UL classified gasoline -resistant pipe -joint sealing <br />compound (non -hardening). Tighten until a complete <br />seal is obtained. Additional tightening may cause the <br />body to crack and allow product leakage at test or in <br />service. (Torque specification is 9-11 foot-pounds.) <br />Page 2 <br />
