1. By applying voltage to the coil 2. By opening the valves manually(when the manual override accessory is fitted) 3. By connecting the Danfoss permanent mag- net (see Tools, page 40) Note that the manual opening unit is not supplied as standard, but as an accessory for EV220B 15-50 valves (see page 31).

Installation Installing the coil Danfoss recommends that the solenoid valve be in- stalled with coil upwards. This minimises the risk of dirt collecting in the armature tube. If “clean” media is used, i.e. media containing no dirtpar- ticles, the solenoid valve will operate when installed in the orientation as shown below.
Page 12
Installation Coil Check to ensure that the coil operating voltage is correct (see text on coil, in “Volt”). Also ensure that the data is correct (voltage and frequency) and matches the supply. If the two sets of data do not correspond, the coil might burn out.
This enables clarification as to whether there is sufficient pressure differential to be able to open a servo-operated valve. The following types of valves are well-suited for use in open systems: EV210B, EV210A, EV310B and EV310A direct -operated solenoid valves EV220B, EV220A and EV225B servo-operated solenoid valves Closed circuit (cirulating system) In a closed circuit system the pressure conditions are undefined.

The product range includes valves for special application, designed for pressures of up to 80 bar. The large standard range combined with these valves enable the use of Danfoss solenoid valves for all types of systems, wether with normal or more extreme inlet pressures.

How to Choose The characteristics of the medium The valve have been designed for use with different media. In general the following is valid: Valves containing EPDM-rubber are suitable for water and steam*. Valves containing FKM-/NBR-rubber are suitable for oil and air. Incorrect use of valve types 1) If a valve containing EPDM-rubber is used for a medium containing oil (compressed air normally contains particles of oil from the compressor)
