032U7141 Danfoss – EV220B 40 Servo-Operated Solenoid Valve, G 1 1/2, NC, FKM Seal
The Danfoss 032U7141 is the EV220B 40, a large-bore, normally closed, 2/2-way servo-operated solenoid valve with a G 1 1/2 connection, a brass body and an FKM seal. Its specification key is EV220B 40B G 112F NC000. With a Kv of 24 m³/h, it is designed for high flows of oil, compressed air, vacuum and neutral media, and water up to 60 °C. Typical uses include compressed-air mains and receiver outlets, large lubrication and oil-transfer lines, cooling-water headers and industrial process equipment, where smaller EV220B sizes cannot deliver the flow needed.

Soft Closing for Large Pipelines
Large servo-operated valves like the EV220B 40 open and close relatively slowly, at about 1.5 s to open and 4 s to close on water. This gentle action helps to reduce water hammer and pressure shocks in large-diameter lines.
Supplied Without Coil
The valve is supplied as a body without coil. Order a Danfoss coil for type B actuators (13.5 mm) in your required supply voltage.
