THREE-WAY ZONE BALL VALVE - www.regulus.eu
1. Introduction
A 3-way zone valve with electric actuator (230V, 50Hz), permitting manual control. It is usually
used in heating and solar thermal systems. The actuator is attached to the valve with four M5 nuts
(spanner size 8) and can be removed without the need to remove the valve. The valve does not
interrupt the ow of uid through the common port during switching. The direction of uid ow is
indicated by the actuator control knob. Fluid can ow in either direction through the valve (common
port can be used either as inlet or outlet).

Direction of ow through the valve
Direction of ow through the valve is indicated by the actuator control knob or by the groove on the
valve spindle visible after removing the actuator:

3. Actuator
3.1. Actuator Electrical Wiring
The actuator is controlled by the switch-over contact of a controller (three-point wiring), 230 V, 50
Hz. When one controller output closes, the valve rotates clockwise, when the other output closes, it
rotates anti-clockwise. The actuator is equipped with end stops so the controller can be permanently
switched through one of the outputs into the actuator. However, the controller must never close both
the outputs for valve control simultaneously, otherwise the actuator will get damaged.

3.2. Actuator Control
The actuator can be switched between automatic and manual mode. In automatic mode, its direc-
tion of rotation is indicated by light indicators. In manual mode, the valve can be turned using the
control knob.
The control knob shows the position of the valve using the coloured eld. The colour of the uid ow
direction on the label corresponds to the colour indicated by the control knob.

3.3. Actuator Placing
The default position of the actuator is such that the valve can be installed in the piping without
removing the actuator. If required, the actuator can be removed and tted in a dierent position
(in quarter turns) - see the g. The label shall be then carefully removed and rotated to the correct
position according to the ports arrangement.

4.1. Valve Adjustment Options
A) Factory adjustment
The default setting of the actuator is with the knob turned to show blue field. After the contact is
switched in a controller or a thermostat, the valve turns clockwise and the red field is shown by the
knob. After the contact is switched again, the valve returns to its default position. A label showing
the fluid flow direction in colour corresponding to the colour shown by the knob position is placed on
the actuator.
Default position Default position Label on the actuator
Blue indicator Red indicator
Warning: Other settings than the default factory adjustment are not possible.

5.1. Valve Adjustment Options
A) Factory adjustment
The default setting of the actuator is with the knob turned to show blue field and the fluid flows
straight through the valve. After the contact in a controller is switched, the valve turns clockwise.
The red field is shown by the knob and the fluid is directed through 90 degrees in the valve. After
the contact is switched again, the valve returns to its default position. A label showing the fluid flow
direction in colour corresponding to the colour shown by the knob position is placed on the actuator.

B) Changing the common port of the valve
If necessary, the common port of the valve can be changed. In the default position the knob will
show the red eld and the uid will ow straight through the valve. After the contact in a controller
is switched, the valve turns anti-clockwise. The blue eld will be shown and the uid will be directed
through 90 degrees in the valve. After the contact is switched again, the valve returns to its default
position.
How to change the default position of the valve
1. Switch the valve to manual mode and turn the knob to the default factory position (blue eld).
2. Unscrew the four M5 nuts (spanner size 8) and remove the actuator from the valve.
3. Turn the knob by a quarter turn to show the red eld.
4. Fit the actuator on the valve and tighten it with the four M5 nuts.
5. Switch the actuator to automatic mode.
6. Remove the label from the actuator and replace it with the enclosed label showing the
corresponding setting.

Red indicator Blue indicator
6. Permissible and Prohibited Positions
WARNING - Important
Installation of the valve in a position where the actuator is located below the valve
is prohibited.
