Recommended Closing Procedure: Using an appropriate wrench, tighten the stem by pulling the wrench to the closed position. When the valve is closed as tight as the wrench can be pulled, give the wrench a closing slap with the gloved palm of the hand. The minimum closing torque for this valve is 35 ft-lbs. but it is not uncommon for some valves to require as much as 60 to 80 ft-lbs. to fully seal.
