2 Functions

2.1 Function, NC

Coil voltage disconnected

When voltage is disconnected, the armature spring (2) presses the armature (3) down against the pilot orice (4). Pressure builds up over the diaphragm (5) via the equalizing orice (7). The diaphragm closes the main orice (6) as soon as the pressure over the diaphragm equals the inlet pressure. The valve stays closed for as long as voltage remains disconnected.

Coil voltage connected (open)

When voltage is applied to the coil (1), the pilot orice (4) is opened. Since the pilot orice is larger than the equalizing orice (7), pressure over the diaphragm (5) falls and the diaphragm is lifted clear of the main orice (6). The valve stays open for as long as the required least dierential pressure is present and voltage is applied to the coil.

Figure 1: Function, NC

2.2 Function, NO

Coil voltage disconnected (Open)

When voltage is disconnected, the pilot orice (4) is opened. Since the pilot orice is larger than the equalizing orice (6), pressure over the diaphragm (5) falls and the diaphragm is lifted clear of the main orice (7). The valve stays open for as long as the required minimum dierential pressure is present and voltage is applied to the coil.

Coil voltage connected (Close)

When voltage is applied to the coil (1), the armature spring (2) presses the armature (3) down against the pilot

orice (4). Pressure builds up over the diaphragm (5) via the equalizing orice (6). The diaphragm closes the main orice (7) as soon as the pressure over the diaphragm equals the inlet pressure. The valve stays closed for as long as

voltage remains disconnected.

3 Applications

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

Figure 3: 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 4: 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.
