Solenoid valves Type EVU for fluorinated refrigerants

EVU solenoid valves are designed to ﬁt into compact refrigeration systems. Available in direct and servo 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:

y commercial refrigeration systems y refrigeration appliances y liquid coolers y ice cube machines y mobile refrigeration systems y heat pump systems y 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.

Features

Approvals

y Compact construction small dimensions,

low weight for both valve and coil.

y Semi-hermetic construction. Metallic sealing

between armature tube and valve body. Bimetal connections to the brass housing Beneﬁts:

– high strength of joints and high

vibration resistance

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

y Bimetal connections simple, fast soldering

without the need of wet cloth or refrigration pliers.

• UL Recognized Component (Canadian and US)

y Direct and servo operated mini piston compact

solenoid valve.

y Universal application for

− liquid, suction, and hot gas applications

− reduced power consumption

y Simple and fast mounting of coil

− clip - ON / OFF

y Small encapsulated coils with long life time

under extreme conditions.

y Refrigerants:

R744, R22 / R407C, R404A / R507, R410A, R134a, R407A, R23. For other refrigerants, please contact Danfoss.

y Large MOPD range − up to 36 bar.

 Cv value is the water ﬂow in [gal / min] at a pressure drop across valve p = 1 psi, ρ = 10 lbs / gal

 MOPD for media in gas form is approximately 14 psi greater

 For coil 208 – 240 V, 60 Hz, MOPD is 250 psi

MOPD (Max. Opening Pressure Diﬀerential) is measured with highest media and ambient temperature and 15% below nominal voltage

Metric conversions:

• 1 psi = 0.07 bar

•5/9 (t1 °F -32) = 12 °C

• 1 TR = 3.5 Kw
