3. 4 DuraSeal Valves are DIB 1 valves and as a result trap internal pressure This pressure is subject to thermal expansion and can cause a thermal lock To prevent pressure build up in the body cavity a DTR is recommended 5 5 On valves equipped with DTRs the body isolation valve found behind the body flange must be left open during normal use The check valve will open at 25 psi differential pressure on all valves and can relieve to any location normally upstream side of the valve DTRs are also 2 provided with a manual body bleed valve to check valve seal integrity 5 6 9 7 www FranklinValve com Franklin Valve L P 500 Northpark Central Dr Suite 100 FRANK LI N Houston Texas 77073 USA 1 713 812 7100 All DuraSeal Valves are manufactured with either an integral handwheel operator or an integral right angle worm gear operator Both operators are connected to valve stem by a coupling pin This pin is visible when the valve is in the closed position and lines up with cast holes on the side of the lower gear housing The valve operator can be removed for inspection by simply driving the coupling pin out and removing the mounting bolts Confirming seal integrity with DBB 5 7 1 Ensure that location and conditions are safe for bleeding line fluid with appropriate fluid capture if applicable 5 7 2 Close the valve fully 5 7 3 Drain or bleed body cavity 5 7 4 lf there is an indicated leak follow 6 8 5 8 Valve
