D. Cycle the actuator/valve to the counter-clockwise
end of travel and measure to determine if the valve is
in the proper position. (In most applications this will
be fully opened.)
E. If the valve is not in the correct counter-clockwise
position, turn the left stop adjustment screw (2) IN to
reduce actuator travel, or OUT to increase actuator
travel.
F. When the correct counter-clockwise position is
obtained, hold the adjusting screw (2) stationary
while tightening the lock nut (4).
6. Position Indicator (19, 39) Assembly. (Figure 18):
A. Fit position indicator (19) on the shaft (60), verifying
that it indicates the correct actuator position.
B. Tighten cap screw (39) to secure the position indica-
tor.
7. Setting 100% Adjustable Stop (If applicable).
(Figure 19):
To limit the rotation on the stroke beyond the standard ±5°
of a VPVL actuator, a stainless steel 100% adjustable travel
stop option can be added. The stops, located in the end
caps, allow the valve position to be set anywhere between
full closed and full open. This option limits travel of only the
counter-clockwise stroke for standard double-acting and
spring-closed units. Follow the proceeding steps in order to
set the 100% adjustable travel stops.
