ACTUATOR MODIFICATIONS
6.1 Adjusting the Actuator Stroke
If for any reason the actuator will not rotate the valve rotor completely, or if you
have reason to believe that the actuator is stroking too far, refer to the directions
below to adjust the actuator for slightly more or less rotation than is supplied by
the factory.
Because of differing amounts of play designed into the components, the actuator
stroke
must be checked any time that the actuator is refitted to operate with
different mounting hardware than it originally received at the factory: i.e., a standoff
assembly used with an actuator that originally had closemount hardware, or
closemount hardware used with an actuator originally supplied with a standoff
assembly.
Valve alignment should always be checked before adjusting the actuator stroke to
confirm that the rotor pin is not contacting either side of the cutout. Since it is
difficult to see whether the stroke is too great, adjust the stroke by very small
increments so that you can stop as soon as the rotor pin just contacts both sides
of the cutout.
NOTE: This adjustment cannot make a 36° actuator into a 60° actuator. To do
that, see Section 6.2, Actuator Conversion.
1. Step the actuator to the LOAD position. Remove the valve and its mounting
hardware from the actuator.
For a closemount valve, (Figure 8, page 9) use the 7/64 hex driver to
loosen the HWSC-SC6-8B/socket head screw (6-32 x 5/8") in the stainless
CR4/clamp ring. Pull off the valve and its attached black-anodized
CR41/closemount standoff. With a 9/64 hex driver remove the two HWSC-
SC8-6TDH/modified socket head screws (8-32 x 3/8") which hold the clamp
ring to the actuator.
For a valve on a standoff, (Figure 9, page 10) use the 9/64 hex driver to
loosen the HWSC-SC8-8B/socket-head screw (8-32 x 5/8") in the black
anodized CR3/clamp ring on the actuator. Pull off the standoff with the valve
attached. The same hex driver will remove the two HWSC-SC8-6/socket-
head screws (8-32 x 3/8") which hold the clamp ring to the actuator.
2. Unplug the actuator. Use a 9/64 hex driver to remove the four HWSC-
SC8-6/screws (8-32 x 3/8") which hold the black right angle mounting
bracket to the actuator body. (See Figure 13)
3. Remove the four HWSC-PL4-4/screws (4-40 x 1/4") holding the outer
cover and pull the cover back 1 to 2 inches. It may be necessary to
remove the two strain reliefs labeled REMOTE SWITCHING and
MANUAL SWITCHING. Do not remove the bottom strain relief labeled
120V AC 50/60 HZ.
