Handling
For valves with handwheel actuators, a sling or chain can be wrapped through the rim of the hand-
wheel. For chainwheel actuators, a sling can be wrapped in the area between the yoke/legs and the
chainwheel/guide assembly. This would be in conjunction with lifting from the valve body as well. See
Figure 3.

Suggested lifting options are as shown below to lift valve assemblies that are in a vertical orientation.
For valves with bevel gear actuators, wrap slings or chains around the top of each leg. Use caution
not to put any side load on the bevel gear input shaft or on the valve's threaded stem. See Figure 4.
For valves with pneumatic cylinder actuators, wrap slings around the top of each leg. Use caution to
not bump, dent or damage the cylinder tube and avoid any side load on the cylinder piston rod. DO
NOT utilize the cylinder tie-rod ends to lift. See Figure 5.
For valves with handwheel or chainwheel actuators, wrap slings or chains around the top of the each
leg or yoke side. Use caution to not put any side load on the valve's threaded stem. See Figure 6.
