DPI models only
Some actuators are equipped with a DPI (Direct Position Indicator). The DPI on KC Actuators will be
either DPI-E or DPI-C.
The tests described in the following can be made on the actuator when mounted on the valve bon-
net/stem as well as when dismounted.

Test of DPI-E, On/Off signals
1. Connect a hydraulic hand
pump (if not connected
already) by dismounting
the caps (d) from the two
hydraulic connection fit-
tings and connect the
pump hoses to fittings A
and B.
2. Make sure the visual indi-
cator (c) shows closed.
3. Operate the hand pump
and observe that the spin-
dle (e) moves in (1 = actu-
ator is open) and out (2 =
actuator is closed).
4. Ensure that the actuator
is in position 2 = closed
(the spindle is in max.
‘out’ position) before con-
tinuing with step 5.
