SE18F24
Valve actuator for 3-point control
SE18F24 is a valve actuator designed for control of AB Industrietechnik
valves. For more info, see the product sheet of each valve. The actua-
tor can also be combined with other brands of valves using adapter
kits. The actuator can be operated manually.

Installation
If the valve stem lock and valve throat adaptor are not already mounted
on the valve, mount them. Pull the valve stem out as far as possible.
Remove the screws (hex key 6 mm) and clamp from the actuator yoke.
Depress the spring-loaded tab on the drive rod coupling device and fit the
valve stem into the coupling.
Release the tab to connect the valve to the actuator. The position of the
yoke on the valve stem adaptor must be adjusted so that the clamp screw
holes line up with the groove in the valve throat adaptor. If the drive rod
needs to be moved in or out for this, depress the central button of the
control knob and turn it clockwise to extend the drive rod and counter-
clockwise to retract it (see Manual override). Mount the screws and the
clamp. Tighten the screws until the actuator is firmly attached.
Disassembly takes place in reverse order.

Calibration
Field calibration is not required. Once the valve reaches its endpoint, a
force builds up. When the force reaches the set level, a lever within the
actuator operates a switch that stops the motor.
Manual override
To manually set the valve position, first depress the central part of
the button until it clicks and remains depressed (1 in the figure). This
disengages the gears and also cuts the power to the motor. Then the
valve position can be changed manually by turning the button (2 in
the figure). Clockwise rotation will extend the drive rod and anti-clock
-
wise will retract it.
To reconnect power, set the button so the flats are in line with the
cutout in the edge of the cover, Auto position. Then press on the outer
parts of the button (3 in the figure). The central depressed part will
pop out re-engaging the gears and reconnecting the power.
