Mounting Instructions
If the valve is plumbed with Port 2 as the common port and the main body of the
actuator is mounted over Port 2 (standard mounting), there is no need to adjust the
actuator cams.
1. Remove Locking Knob and handle. Set aside for reinstallation later.
2. Remove four (4) screws from the valve. Refer to Fig. 1 (mounting positions) to
determine which screws to remove.
3. On the back side of the actuator, align the smallest slot on the actuator shaft with
the smallest slot on the valve diverter.
4. With the two shafts engaged rotate the actuator until holes on the actuator align
with the screw holes on the cover.
5. Use four (4) ¼-14x1½" long screws (packaged with the actuator) to secure it in
place. Do not overtighten - be careful if using a power screwdriver.
6. Place valve handle on actuator shaft and tighten Locking Knob.
Cam Adjustment
1. When changing the cam settings, move toggle switch at bottom of actuator to
the OFF (center) position.
2. Unscrew and remove Locking Knob and handle from actuator shaft.
3. Remove the four (4) screws which hold the actuator cover on and remove cover.
4. The upper and lower cam are located on the actuator shaft. Slide the cams off the
shaft splines and rotate to the desired position. Refer to the charts on the
previous pages to determine the correct cam setting for your installation. Some
installations may require settings not found on the chart (partial open, partial
close, etc.) All settings are referenced from the small slot on the shaft, which is
always 12 o'clock (Fig. 2). The upper cam effects the clockwise position stop
point. The lower cam to effects the counterclockwise rotation stop point.

Using the chart below to determine correct cam setting using standard clock posi-
tions. Refer to the "Cam Adjustment" section in this manual to change upper and
lower cam positions if necessary.
Two Port Valve
The Model GVA-24 Actuator may be mounted to the valve in four different positions.
In all cases, the cam settings are the same. Refer to the chart below for cam settings
for 2 way valves.
