Installation and Operation Manual
THREE-WAY ZONE BALL VALVE

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 flow of fluid through the common port during switching. The direction of fluid flow is indicated by the actuator control lever. Fluid can flow in either direction through the valve (common port can be used either as inlet or outlet).

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

 Actuator

3.1. Actuator Electrical Wiring
The actuator is controlled by the switching contact of the controller or thermostat 230V, 50Hz.
Permanent power supply is applied to terminals 1 and 2. The switched live is connected to terminal 3.
Wiring diagram
3.2. Actuator Control
The actuator can be switched between automatic and manual mode. In automatic mode, its direction of rotation is indicated by light indicators. In manual mode, the valve can be turned using the control lever.
The control lever shows the position of the valve using the coloured field. The colour of the fluid flow direction on the label corresponds to the colour indicated by the control lever.
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 fitted in a different position (in quarter turns) – see the fig. 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 lever turned into the blue field (OFF position). After the switched live is connected (ON), the valve turns clockwise and the red field is shown by the lever. After the switched live is disconnected (OFF), the valve returns to its default position. A label showing the fluid flow direction in colour corresponding to the lever position is placed on the actuator.

B) Swapping the ON and OFF positions of the valve
If necessary, the ON and OFF valve positions can be swapped. In the default position (OFF) the lever will be turned to the red field. After the switched live is connected (ON), the valve turns anti-clockwise and the blue field is shown by the lever. After the switched live is disconnected, the valve returns to its default position (OFF).

How to change the default position of the valve

1. Switch the actuator to manual mode and turn the lever by a quarter turn into the red field.
2. Change the direction of rotation of the actuator according to Chapter 6.
3. Switch the actuator to automatic mode.
4. Remove the label from the actuator and replace it with the enclosed label showing the corresponding setting.

5.1. Valve Adjustment Options
A) Factory adjustment
The default setting of the actuator is with the lever turned to the blue field (OFF position) and the fluid flows straight through the valve. After the switched live is connected (ON), the valve turns clockwise. The lever is turned to the red field and the fluid is directed through 90 degrees in the valve. After the switched live is disconnected (OFF), the valve returns to its default position. A label showing the fluid flow direction in colour corresponding to the colour corresponding to the lever position is placed on the actuator.

Other Adjustment Options
The default valve adjustment can be changed in three different ways.
B) Swapping the ON and OFF positions of the valve
If necessary, the ON and OFF valve positions can be swapped. In the default position (OFF) the lever is turned to the red field and the fluid will be directed through 90 degrees in the valve. After the switched live is connected (ON), the valve turns anti-clockwise, the blue field is shown and the fluid will flow straight through the valve. After the switched live is disconnected, the valve returns to its default position (OFF).

How to change the default position of the valve

1. Switch the actuator to manual mode and turn the lever by a quarter turn to show the red field.
2. Change the direction of rotation of the actuator according to Chapter 6.
3. Switch the actuator to automatic mode.
4. Remove the label from the actuator and replace it with the enclosed label showing the corresponding setting.

C) Changing the common port of the valve
If necessary, the common port of the valve can be changed. In the default position (OFF) the lever is turned to the red field and the fluid will flow straight through the valve. After the switched live is connected (ON), the valve turns anti-clockwise. The blue field will be shown and the fluid will be directed through 90 degrees in the valve. After the switched live is disconnected, the valve returns to its default position (OFF).

How to change the default position of the valve

1. Switch the valve to manual mode and turn the lever to the default factory position (blue field).
2. Unscrew the four M5 nuts (spanner size 8) and remove the actuator from the valve.
3. Turn the lever by a quarter turn to show the red field.
4. Fit the actuator on the valve and tighten it with the four M5 nuts.
5. Change the direction of rotation of the actuator according to Chapter 6.
6. Switch the actuator to automatic mode.
7. Remove the label from the actuator and replace it with the enclosed label showing the corresponding setting.

D) Changing the ON and OFF positions and common port of the valve
If necessary, the ON and OFF valve positions and the common port of the valve can be changed. In the default position (OFF) the lever is turned to the blue field and the fluid will be directed through 90 degrees in the valve. After the switched live is connected (ON), the valve turns clockwise. The red field will be shown and the fluid will flow straight through the valve. After the switched live is disconnected (OFF), 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 lever to the default factory position (blue field).
2. Unscrew the four M5 nuts (spanner size 8) and remove the actuator from the valve.
3. Turn the lever by a quarter turn to point to the red field.
4. Fit the actuator on the valve and tighten it with the four M5 nuts.
5. Turn the lever by a quarter turn to point to the blue field.
6. Switch the actuator to automatic mode.
7. Remove the label from the actuator and replace it with the enclosed label showing the corresponding setting.

Changing the direction of rotation of the actuator

In the factory setting, the actuator without control voltage shows the blue field. After the control voltage is applied, the actuator starts turning clockwise and the red field is shown. The jumper is placed vertically. After the jumper is turned to a horizontal position, the actuator without control voltage will show the red field. After the control voltage is applied, the actuator starts turning anti-clockwise and the blue field is shown.

1. Switch off the supply voltage, set the manual control, unscrew and remove the actuator cover.
2. Locate the jumper – see the red marked area in the picture.
3. In the factory setting, the jumper is placed vertically. The actuator turns clockwise.
4. Turning the jumper by 90 deg. to the horizontal position will change the direction of rotation. The actuator now turns anti-clockwise.

Having placed the jumper to the desired position, re-install the actuator cover and switch the actuator to automatic mode.

Permissible and prohibited positions

WARNING – Important
Installation of the valve in a position where the actuator is located below the valve is prohibited.
