VPI PRESSURE INDEPENDENT CONTROL VALVES & ACTUATORS
11 31-00383-01
Installation of Actuators compatible with DN50 – 250
Procedure to install the Actuator
The procedure to install the valve is as follows:
1. Grease the O-ring on the spindle adaptor with
silicone grease before placing the spindle adaptor
on the valve spindle.
2. Then place the actuator on the spindle adaptor
and place the three actuators “legs” into the three
holes in the mounting bracket as shown below.
Make sure that the snap ring is clicked onto the
mounting bracket, so that the snap ring is locked
at the top of the mounting bracket, but still able to
rotate.
3. Then finger turns the snap ring counterclockwise
(upside view) approximately 1/6 of a turn until its
stop points touch the actuator “legs” and the
mounting is a lock with a (small) click. Do not use
additional tools.

Mounting Position
The actuators can be mounted in any position (IP54 is
dependent upon orientation; see Figure 17). Choose a
mounting position permitting easy access to cables.

Procedure to remove the Actuator
The Steps to remove the actuator is as follows:
1. Make sure if the valve is in open position for easy
removal of the actuator.
2. Turn the Snap ring in the clockwise direction until
the actuator is loosened.
3. Lift the actuator up, to remove the actuator.
