Data Sheet
Solenoid valve Type EV220W
Indirect servo operated for compact installation in various applications
EV220W is a range of compact indirect servo­operated 2/2 way solenoid valves with connections from 3/8” to 2”, especially designed for use within a limited space. This range has been designed for use within various markets, such as, the Industrial and HVAC markets, which demand an easy and reliable valve that is easy to setup and use.
• For water, oil, compressed air and similar neutral media
• NBR for air and oil
• WRAS approved with EPDM sealing; 0 – 90 °C NC version 0 – 50 °C NO version
• Standard equipped with clip on coil for dry and humid environments
• Enclosure: IP65

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 (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.
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 (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.
Figure 5: Caution: Coil Risk
WARNING:
Risk of burns/re if used for a continuous power-on time through hot coil surface.
• l Do not touch the coil with bare hands.
• l Keep the coil away from highly ammable substances with low ignition point.
