How an EVU servo-operated (without 0.25" US spade) valve works

How an EVU servo-operated (without 0.25″ US spade) valve works, including the refrigerant flow and solenoid state at every step. The Danfoss EVU series solenoid valves are for use with a wide range of fluorinated refrigerants, as well as natural refrigerants like R290 and R744

How an EVU servo-operated valve works

Watch how an EVU servo-operated valve works, including the refrigerant flow and solenoid state at every step. The Danfoss EVU series of solenoid valves are for use with a wide range of fluorinated refrigerants, as well as natural refrigerants like R290 and R744.  

How an EVU 1 direct-operated (without 0.25" US spade) valve works

Watch how an EVU 1 direct-operated (without 0.25″ US spade) valve works, including the refrigerant flow and solenoid state at every step. The Danfoss EVU series of solenoid valves is for use with a wide range of fluorinated refrigerants, as well as natural refrigerants like R290 and R744. 

How EVR 32 and 40 servo-operated solenoid valves work

Watch how EVR 32 and 40 servo-operated solenoid valves work. The Danfoss EVR series of solenoid valves is for use with non-aggressive and fluorinated refrigerants. The EVR 32 and 40 are NC (normally closed) pilot-controlled valves.  

How an EVR 25 servo-operated solenoid valve works

Watch how an EVR 25 servo-operated solenoid valve works. The Danfoss EVR series of solenoid valves is for use with non-aggressive and fluorinated refrigerants. The EVR 25 is a servo-assisted NC (normally closed) valve that can operate with either an a.c. or d.c. coil. 

How EVR 15 and 20 servo-operated solenoid valves work

Watch how EVR 15 and 20 servo-operated solenoid valves work. The Danfoss EVR series of solenoid valves is for use with non-aggressive and fluorinated refrigerants. The EVR 15 and 20 are servo-assisted valves and can be either NC (normally closed) or NO (normally open).  

How an EVR 2 direct-operated solenoid valve works

Watch how an EVR 2 direct-operated solenoid valve works. The Danfoss EVR series of solenoid valves is for use with non-aggressive and fluorinated refrigerants. The EVR 2 is an NC (normally closed) directly controlled valve.  

EVU1 Direct Operated

Electromagnetic valve. Both valve and coil are compact and lightweight. Semi-hermetic construction. Stainless steel armature tube top part with a metal gasket. Welded bimetal connections on the brass housing.

Assisted Lift Servo Operated Solenoid Valve (EVRAT 20)

Watch the introduction of Electromagnetic Valve. Controls the flow of refrigerant in the refrigeration system. Can be used for liquid, suction and hot gas lines with ammonia or fluorinated refrigerants. These valves are supplied complete or as separate components.

Servo Operated Solenoid Valve – EVRA 32 & 40

The servo piston with main valve plate closes against the valve seat by means of the differential pressure between the inlet and outlet side of the valve and the force of the compression spring.

Direct Operated Solenoid Valve EVRA3

Watch the introduction of Electromagnetic Valve. Controls the flow of refrigerant in the refrigeration system. Can be used for liquid, suction and hot gas lines with ammonia or fluorinated refrigerants. These valves are supplied complete or as separate components.

Danfoss Learning – Cold Room Training Program

Discover the core principles of the cold chain and how it is used to preserve food in a better way. In this training program, you’ll learn about the different types of cold rooms and their applications. You’ll also be introduced to the factors you need to consider when calculating cooling load, as well as how to perform a cooling load calculation using the Coolselector®2 software.  

Servo operated solenoid valve – EVRA 25

Electromagnetic servo operated piston valves.

Servo Operated Solenoid Valve – EVRA 20

The Electromagnetic Valve controls the flow of refrigerant in a refrigeration system.

AKVA – Expansion Valve
The AKVA valves are electrically operated expansion valves designed for refrigeration applications. The AKVA valves can be used with HCFC, HFC, CO2 and Ammonia refrigerants. The AKVA valves are normally controlled by controllers with an On/Off electrical signal. The AKVA 20 valves cover a capacity range from 500 kW to 3150 kW (R 717) and are divided up into 5 capacity ranges. The AKVA 20 valve has weld connections.
T2 Thermostatic Expansion Valves – Danfoss

Watch how a Danfoss T2/TE 2 thermostatic expansion valve (TXV) works, including how the bulb sensor and spring work together to control the refrigerant feed to the evaporator based on the superheat.
