4. Assembly of Stop Screws (2) and Stroke
Adjustment. (Figure 17):
A. Insert the nut (4), washer (3), and o-ring (11) onto the
stop screws (2).
B. Screw the stop screws (2) into the body (50).
5. External Travel Stop Adjustment, (Figure 17):
The stop adjustment screw (2) to the right controls the
clockwise end of travel. The stop adjustment screw (2) to
the left controls the counter-clockwise end of travel.
A. Cycle the actuator/valve to the clockwise end of
travel and measure to determine if the valve is in
the proper position. (In most applications this will be
fully closed.)
B. If the valve is not in the correct clockwise position,
turn the right stop adjustment screw (2) IN to reduce
actuator travel, or OUT to increase actuator travel.
C. When the correct clockwise position is obtained,
hold the adjusting screw (2) stationary while tight-
ening the lock nut (4).
