Danfoss 032U7150 EV220B 50 Solenoid Valve G 2 NC 40 m3/h
Description
EV220B 50: the largest threaded EV220B with 40 m3/h flow
Danfoss 032U7150 is the EV220B 50, a G 2 brass-body, normally closed solenoid valve with a 50 mm orifice and a Kv of 40 m3/h (Cv 46.2). It is the top of the threaded EV220B 15 to 50 range and a common pick for fill lines, wash-down headers and process water feed on skids where flanged valves would be oversized.
The weight of 4.69 kg is notable for a threaded valve, and the pipe should be supported on both sides rather than carrying the body. The working pressure is 12 bar, the test pressure 18 bar, and the minimum differential 0.3 bar.

Slow, soft closing for big water lines
Closing takes roughly ten seconds and opening five seconds on water, as estimated by Danfoss. That long time protects the pipeline from water hammer, yet it means you must allow for the volume that flows after the coil is de-energised if the valve is used for dosing or for tank filling with a level switch.
The data sheet offers an optional equalising orifice to adapt the closing behaviour; the store lists it as an option. Do not modify it without the guidance in the data sheet. The medium range of -30 to 120 C and the maximum viscosity of 50 cSt apply.
Installation and ordering notes
Use a strainer, keep a straight run of pipe upstream and make sure the arrow follows the flow. A coil must be ordered separately, along with the connector, and the voltage should match the plant supply. The approvals as listed include CE, DNV GL CG-0339 and GL, but confirm the approval you need for your application.
Seven Star LLC is an independent supplier in Muscat and can quote 032U7150 with coil and plug when you send the details.
Because the valve is heavy for a threaded part, an unsupported pipe will place stress on the thread and may cause leaks after some months. Add a pipe clamp each side, use thread sealant suitable for the medium, and tighten with a wrench on the body flats only. Plan the coil position so that the housing can be removed without draining the line.
Note also that the minimum differential of 0.3 bar means the valve will not open on gravity-fed lines with a very low head, so check the available head before choosing this model for a tank-to-tank transfer.
When you receive 032U7150, compare the code on the label with the order and with this page before installation. Report any difference immediately, keep the original packing for the first days, and store the unit dry and clean until the installation crew is ready to start.

About brand
From its headquarters in Nordborg, Denmark, where it was founded in 1933, Danfoss makes the drives, valves and sensors found in pump rooms, chiller plants and cold stores. Its blue VLT frequency converters are probably the most familiar of them.
Seven Star LLC lists Danfoss VLT drives, pressure transmitters, refrigeration valves and HVAC control valves, and supplies them to contractors and plant owners in Oman against the exact code number on the label.
Danfoss product families on this page
Among the VLT drives listed, three are each aimed at a different duty: the VLT HVAC Drive FC 102 for fans and building services, the VLT AQUA Drive FC 202 for water and wastewater pumping, and the VLT AutomationDrive FC 302 for general industrial machinery. The LCP 12 control panel with potentiometer (code number 132B0101) is also listed; Danfoss specifies it for the VLT Micro Drive FC 51. In pressure measurement there are the MBS 3000 general purpose transmitter and the MBS 5100. Valves include the AB-QM pressure independent control valve in DN 15 to DN 250, the EVR 25 servo-operated solenoid valve and the ICV pilot-operated valve for industrial refrigeration.
Where Danfoss equipment is used
District cooling and chilled water plants, air handling units, booster and irrigation pump stations, desalination and wastewater works, ammonia and CO2 refrigeration plants, food storage and marine engine rooms are the usual places. Demand in the GCC is driven largely by cooling and water.
Ordering Danfoss parts: what we need
Every Danfoss product has a code number, and drives also carry a long type code string on the label. Send both. For a drive we need the motor power and current, the mains voltage, enclosure rating, any fieldbus or option card and the filter class. For an MBS transmitter give the pressure span, output signal, pressure connection and electrical connection. For valves give the size, connection type, coil voltage where relevant and the refrigerant or medium.
