available in sizes 30, 40, 50, 80, and 100, and can be
mounted on Fisher Controls easy-e
The Type 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
Type 1008 handwheel actuator except size 100 are
reversible following the Reversing Handwheel proce-
dures.
