Valve actuator for 0(2)...10 V control
RVAN5-24A is a valve actuator designed for control of Regin valves.
The actuator has automatic self stroke adjustment and can be oper-
ated manually.

Installation
If the valve stem adaptor and valve throat adaptor are not already mount-
ed on the valve, mount them. Pull the valve stem out as far as possible.
Remove the locking bolt (U-bolt) from the actuator yoke. Insert the valve
stem into the yoke and make sure that the stem adaptor engages the hole
in the angled iron of the actuator drive spindle.
The groove in the valve throat adaptor must be made to line up with the
U-bolt mounting holes on the actuator. If the spindle needs moving in or
out for this to happen, depress the central part of the manual button and
turn it clockwise for the actuator spindle to extend, and anti-clockwise for
it to retract (see Manual override). When the valve is in the correct posi-
tion, insert the U-bolt. Tighten the bolt nuts until the valve is firmly gripped.
Disassembly in reverse order.

Stroke and end position calibration
Stroke and end position calibration is not necessary due to a construction
utilizing end position stops. When the valve reaches the end position, a
force is generated.
Once the force of the actuator reaches a predefined
level, the limit switch automatically halts the drive motor.
Override
Activation of the override input will force the valve to the maximum
open position.
Manual override
To manually set the valve position, first depress the central part of the
knob, until it clicks and remains depressed (1 in the figure). Then the
valve position can be changed manually by turning the knob (2 in the
figure). When the knob is turned clockwise, the drive rod is pushed
outwards and when the knob is turned anti-clockwise, the drive rod is
pulled inwards.
To return to normal operation, set the knob so that it is in line with the
text ”Auto” on the cover. Then depress the outer parts of the knob (3
in the figure). The central depressed part will pop out, and the actua
-
tor will return to normal operation.
Note: After any manual operation the actuator will always run through
a zero point calibration.
DIP switches
There are five DIP switches for setting different functions. Follow the
table below for setting the DIP switches.
Adjusted settings will be valid only after the next power-on.
