operated and set. The 1008 handwheel actuator is
available in sizes 30, 40, 50, 80, and 100, and can
be mounted on easy-et valves.
The 1008 handwheel actuator converts rotary motion
of the handwheel to linear motion of the valve plug
stem. Because the stem does not revolve, the valve
plug contacts the same seating surface with each
stroke. Sizes 40, 50, 80, and 100 include two thrust
bearings to make rotation easier.
Turn the handwheel counterclockwise to open the
valve regardless of valve plug action. All sizes of the
1008 handwheel actuator except size 100 are
reversible following the Reversing Handwheel
procedures in this instruction manual.
