Introduction

The EVU solenoid valve series has been developed and constructed for soldering into semi-hermetically sealed refrigeration plant and where demands on small physical dimensions are essential. EVU 1 to 8 are compact hermetically sealed sevo operated solenoid valves for liquid, suction, and hot gas lines with fluorinated refrigerants.

EVU can be used in many different refrigeration systems and is especially designed for:

Traditional refrigeration systems

Liquid coolers

Ice cube machines

Mobile refrigeration systems

Heat pump plant

Air conditioning units

Features Compact construction small dimensions, low weight for both valve and coil.

Hermetic construction. Metallic sealing between armature tube and valve body. Bimetal connections to the brass housing Causes:

− high strength of joints and high vibration resistance

− maximum external tightness within the whole temperature and pressure operation range

Bimetal connections simple, fast soldering without the need of wet cloth or refrigration pliers

Direct and servo operated mini pistoncompact solenoid valve

Universal application for − liquid, suction, and hot gas applications − reduced power consumption

Simple and fast mounting of coil − clip-on/off

Small encapsulated coils with long life time under extreme conditions

Refrigerants R22, R134a, R404A, R507, R407C, R410A, R744 and future refrigerants

Large MOPD range − up to 36 bar

Approvals Underwriter laboratoriesPED (97/23/EC A3.P3)The Low Voltage Directive 73/23/EC with amendments EN 60730-2-8

Technical data RefrigerantsCFC, HCFC, HFC, CO2

Temperature of medium−40 → +105°C max. 130ºC during defrosting

Ambient temperature−40 → +60°C

MOPD operating range0.02 bar up to 36 bar

1) The kv value is the water flow in m3/h at a pressure drop across the valve of 1 bar, ρ = 1000 kg/m3.2) MOPD for media in gas form is approx. 8 bar higher. 3) For coil 208-240V, 60 Hz, MOPD is 17 bar.MOPD is measured with highest media and ambient temperature and 15% below nominal voltage.

EVU is supplied as straightway and angleway solder version. The valve cannot be serviced. The standard coil is available with a 3-core cable connection, DIN plug and 0.25 in. US spade. EVU valves are supplied as separate components, i.e. valve body and coil separately in industrial pack.

Capacities are based on liquid temperature tl = +25°C ahead of evaporator. The table values refer to the evaporator capacity and are given as a function of evaporating temperature te and pressure drop ∆p across valve. Capacities are based on dry, saturated vapour ahead of valve.During operation with superheated vapour ahead of valve, the capacities are reduced by 4% for each 10K superheat.

Design / Function

1. & 5. Solder connection 2. & 4. Solder ring 3. Valve housing 6. Union nut 7. Armature tube 8. Return spring 9. Armature 10. Support ring 11. Pilot plate (servo) 12. Seat plate (servo) 13. Piston (servo)

When current is applied to the coil, the armature (9) is drawn up into the magnetic field and thus lifts the pilot plate (11) and opens for the pilot orifice so that the deenergising 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 orifice opens for full flow. Therefore a minimum differential pressure of 0.02 bar is necessary to open the valve and keep it open.When the current to the coil is switched off, the spring (8) and armature (9) are pressed down to-wards 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 orifice closes. The armature (9) continues its downwards movement untill the pilot orifice on the pilot plate (11) is fully closed.

Servo operated Direct operated

Direct operatedEVU 1 is direct operated. The valve opens direct for full flow when the armature (9) moves up into the magnetic field of the coil.This means that the valve operates with a min. differential pressure, spring force and the weight of the armature. Thus, inlet pressure, spring force and the weight of the armature act to close the valve when the coil is currentless.

Servo operatedEVU 2, to 8 are servo operated solenoid valves with a "floating" piston. Piston and seat plate are here separated and can be moved independent from each other. This servo principle results in a fast operating and compact valve that is able to open against a high differential pressure. The valve closes rather soft, because the pilot system does not fully close before the main orifice has closed. This reduces force effect and wear of material in the valve.When the coil is currentless, the main orifice, seat plate (12) and pilot orifice (on the pilot plate (11)) are closed. The pilot orifice and main orifice are held closed by the armature weight, the armature spring force and the differential pressure between inlet and outlet sides.
