Data sheet

Solenoid valves Type EVU

EVU solenoid valves are designed to fit into compact refrigeration systems. Available in direct and pilot operated versions, they can be applied in liquid, suction, and hot gas lines with fluorinated refrigerants.

EVU solenoid valves can be used in many different refrigeration systems and are specially designed for: commercial refrigeration systems 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, DIN plug and 0.25 US spade.

EVU valve bodies and coils are ordered separately in industrial pack.

Features Compact construction small dimensions, Universal application for low weight for both valve and coil. − liquid, suction, and hot gas applications − reduced power consumption

Semi-hermetic construction. Metallic sealing

between armature tube and valve body. Simple and fast mounting of coil Bimetal connections to the brass − clip-on/off

housing Benefits:

– high strength of joints and high Small encapsulated coils with long life time vibration resistance under extreme conditions.

− maximum external tightness within

the whole temperature and pressure Refrigerants: operation range R744, R22/R407C, R404A/R507, R410A, R134a, R407A, R23. Bimetal connections simple, fast soldering For other refrigerants, please contact Danfoss.

without the need of wet cloth or

refrigration pliers. Large MOPD range − up to 36 bar.

Direct and servo operated mini piston compact solenoid valve.
