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:

yy commercial refrigeration systems yy refrigeration appliances

yy liquid coolers

yy ice cube machines

yy mobile refrigeration systems yy heat pump systems

yy 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.

1) Rated liquid and suction vapor capacity are based on:

-evaporating temperature te = 40 °F

-liquid temperature ahead of valve tl = 100 °F

-pressure drop ∆p across valve

-with liquid ∆p = 2 psi for R134a, ∆p = 3 psi for R22 / R407C, R404A and R507

-with suction vapor ∆p = 1 psi

Metric conversions:

•1 psi = 0.07 bar

•5/9 (t1 °F -32) = 12 °C

•1 TR = 3.5 Kw

•1 in = 25.4 mm

•1 ft = 0.3 m

•1 lb = 0.454 kg

•1 oz = 28.35 gram

•US gal / min = 0.86 m3 / h

Rated hot gas capacity is based on:

-condensing temperature tc = 100 °F

-hot gas temperature th = 140 °F

-pressure drop across valve ∆p = 2 psi

Capacities are based on:

-liquid temperature tl = 100 °F,

-evaporating temperature te = 40 °F,

-superheat temperature (te + 10 °F) = 50 °F.

Correction factors for liquid temperature tl

tl [°F]	80	90	100	110	120
Factor	1.10	1.05	1.00	0.95	0.90

When liquid temperature tl ahead of the expansion valve is other than 100 °F, adjust the table capacities by multiplying them by the appropriate correction factor found in the following table.
