Solenoid valves Type EVU
Normally Closed (NC)
EVU solenoid valves are designed to t into compact refrigeration systems. Available in direct and servo operated versions, they can be applied in liquid, suction, and hot gas lines with uorinated refrigerants.
EVU solenoid valves can be used in many dierent refrigeration systems and are specially designed for:
• Refrigeration appliances
• Liquid coolers
• Ice cube machines
• Mobile refrigeration systems
• Heat pump systems
• Air conditioning units
EVU valves are available in straightway or angleway design. All valves are semi hermetically sealed and are not serviceable. The standard coil is available with 3-core cable connection and DIN plug.
EVU valve bodies and coils are ordered separately.

Solenoid valves, Type EVU
Functions
Figure 1: Direct operated
Figure 2: Servo operated
Direct operated
EVU 1 is direct operated. The valve opens directly for full ow when the armature (9) moves up into the magnetic eld of the coil.
This means that the valve can operate at 0 bar dierential pressure. Thus, inlet pressure and spring force act to close the valve when the coil is currentless.
Servo operated
EVU 2 to 8 are servo operated piston solenoid valves. The servo piston principle results in a fast operating and compact valve that is able to open against a high dierential pressure. The valve closes rather soft, because the pilot system does not fully close before the main orice has closed. This minimizes liquid hammer.
When the coil is currentless, the main orice, seat plate (12) and pilot orice (on the pilot plate (11)) are closed. The pilot orice and main orice are held closed by the armature spring force and the dierential pressure between inlet and outlet sides.
When current is applied to the coil, the armature (9) is drawn up into the magnetic eld and thus lifts the pilot plate (11) and opens for the pilot orice so that the de-energising of the servo chamber (A) starts and the pressure is relieved to the level of the outlet side. As the inlet pressure that acts on the bottom of the piston (13) now is higher than the pressure in the servo chamber (A), the piston is moved upwards and lifts both the pilot plate (11) and the seat plate (12). When the seat plate is lifted, the main orice opens for full ow.
Therefore a minimum dierential pressure of 0.02 bar is necessary to open the valve and keep it open.
When the current to the coil is switched o, the spring (8) forces the armature (9) down towards the pilot plate (11). The pressure in the servo chamber (A) increases and the piston will no longer be able to hold the seat plate (12) in lifted position, by which the main orice closes. The armature (9) continues its downwards movement until the pilot orice on the pilot plate (11) is fully closed.

Valve selection based on capacity calculation
As for extended capacity calculations and valve selection based on capacities and refrigerants, please refer to Coolselector®2. Rated and extended capacities are calculated with the Coolselector®2 calculation engine to ARI standards with the ASEREP equations based on laboratory measurements of selected valves.

Please make sure that there is no spark, arc on the spade connection during the application. If coils are below IPx5, they must be protected against ultraviolet, moisture and major impact, especially the connection of coils.
Always Install a fuse ahead of the coil: rated current: two times of rated current, time lag: medium, to avoid short circuit.
The coil used in an area of not more than pollution degree 2.
Follow the installation guide to mount the coil correctly, and apply o-ring for sealing to prevent moisture penetrating inside the coil.

please follow specic selection criteria stated in the datasheet for these particular refrigerants.
NOTE:
The EVU coil (IP65/67) has NOT been veried ATEX or IECEx or IEC 60079 series zone 2 compliant. This product is only validated for systems in compliance with ISO5149, IEC 60335 (ref. IEC/EN 60079-15). It is the responsibility of the user to verify such compliance. Improper use can cause explosion, re, leakage potentially causing death, personal injury, or damage to property.

NOTE:
The three pins on the coil can be tted with spade tabs, 6.3 mm wide (to DIN 46247). The two current carrying pins can also be tted with spade tabs, 4.8. mm wide. Max. lead cross section: 1.5 mm2. If DIN plug is used (DIN 43650) the leads must be connected in the socket. The socket is tted with a Pg 11 screwed entry for 6 – 12 mm.
