2 Functions

2.1 Function, NC

Coil voltage disconnected (closed):

When the voltage to the coil is disconnected, the armature with the valve plates is pressed down by the closing spring and closes the connection between P and A. At the same time, the connection between ports A and R is opened.

The connection between P and A will be closed for as long as the voltage to the coil is disconnected.

Coil voltage connected (open):

When voltage is applied, the armature with the valve plates is lifted and closes the connection between A and R. At the same time, the connection between P and A is opened.

The connection between P and A will be open for as long as there is voltage to the coil.

2.2 Function, NO

Coil voltage disconnected (open):

When the voltage is disconnected, the armature with the valve plates is pressed down by the opening spring and closes the connection between A and R. At the same time, the connection between ports P and A is open.

The connection between P and A will be open for as long as the voltage to the coil is disconnected.

On valves with manual override the connection between P and A can be closed using a closing screw in the valve body.

Coil voltage connected (closed):

When voltage is applied to the coil, the armature with the valve plates is lifted and closes the connection between P and A. At the same time, the connection between ports A and R is opened.

When the voltage to the coil is disconnected, the armature, with the valve plates, is pressed down by the closing spring and closes the connection between P and A. At the same time, the connection between ports A and R is opened. The connection between P and A will be closed for as long as the voltage to the coil is disconnected. On valves with manual override the connection between P and A can be opened using an opening screw in the valve body.

3 Applications

It is recommended to use a lter in front of the valve. Recommended lter 50 mesh (297 microns).

Figure 1: Filter

In water applications, exercise the valves at least once every 24 hours, meaning change the state of the valve. The valve exercise will minimize the risk of the valve sticking due to calcium carbonate, zinc or iron oxide build-up.

Figure 2: Exercise: Valve on/o

To minimize scaling, and corrosion attack it is recommended that the water passing the valve have the following values:

• Hardness 6 - 18 °dH to avoid scaling (chalk / lime stone build up)

• Conductivity 50 – 800 µS/cm to avoid brass dezincication and corrosion

• Above 25 °C media temperature avoid stagnant water inside the valve to avoid dezincication and corrosion attack
