Quick guide from the manual
This document provides essential technical data and spare parts information for the Danfoss EV220A solenoid valve (NC/NO versions). It is designed to assist users in selecting the correct seal material and coil type based on the specific media and operating pressure requirements of their application.
Technical specifications
The performance of the EV220A valve depends on the correct combination of seal material, media, and pressure differential (Δp). Always verify your specific valve configuration against the following parameters:
- Seal Materials:
- EPDM: Suitable for water.
- NBR: Suitable for water, oil, and air.
- FKM: Suitable for oil, air, and water.
- Temperature Ranges:
- EPDM: -30°C to +100°C.
- NBR: -10°C to +90°C.
- FKM (Oil/Air): 0°C to +100°C.
- FKM (Water): 0°C to +60°C.
- Pressure Differential (Δp): The required pressure differential varies significantly based on the valve size (6-50) and the coil type (AB, AM, AK). Refer to the technical tables in the manual to ensure your system pressure falls within the allowed range for your specific model.
Spare parts and maintenance
The manual includes an exploded view of the NC version to assist with maintenance and part replacement. Spare parts kits are categorized by valve size and seal material. Use the provided code numbers to identify the correct kit for your specific valve.

Practical help
Common problems
Incorrect media compatibility
Ensure the seal material (EPDM, NBR, or FKM) is compatible with the media (Water, Oil, or Air) as specified in the temperature table.
Valve fails to open or close
Verify that the system pressure differential (Δp) is within the specified range for your valve size and coil type.
Before use
- Identify your valve size (6-50).
- Determine the media type (Water, Oil, or Air).
- Select the appropriate seal material (EPDM, NBR, FKM).
- Verify the coil type (AB, AM, AK) and wattage.
- Check the minimum and maximum pressure differential (Δp) requirements.
