Danfoss EV220B 40 | Pilot-Operated 2/2 Solenoid Valve, G1½", 24/110/230V AC/DC
Danfoss EV220B 40 (EV220B-40B0400) pilot-operated 2/2-way solenoid valve. DN40 (G1½"), 0.3-16 bar, brass body, NBR/EPDM/FKM seal options, for water, air, oil.

Product Overview

The Danfoss EV220B 40​ (typically ordered as EV220B-40B0400​ with coil specified separately) is a pilot-operated 2/2-way (normally closed) solenoid valve​ from the EV220B series, designed for automatic shut-off or flow control of neutral and slightly aggressive media. It features a DN40 (1½") BSP threaded connection, a brass body, and is available with NBR, EPDM, or FKM (Viton) seals​ depending on the medium. The valve requires a minimum pressure differential of 0.3 bar​ to shift open (pilot-assisted) and is suitable for water, compressed air, oils, and low-viscosity fluids in HVAC, irrigation, and industrial process lines.

Key Features

  • Pilot-Operated — High Flow in Compact Body:​ Uses line pressure to assist opening, allowing large Kv (≈30 m³/h) with a small coil — energy-efficient vs. direct-lift equivalents.
  • Interchangeable Seals:​ NBR standard for water/air; EPDM for hot water/steam traces; FKM for oils/solvents — select by application.
  • Modular Coil System:​ Coil (voltage/wattage) ordered separately — one valve body serves multiple voltages (24V DC, 24V AC, 110V AC, 230V AC).
  • WRAS Approval (NBR Version):​ Suitable for potable water systems in the UK/EU (check local certification requirements).

Applications

  • HVAC & Building Services:​ Chilled/hot water zone control, boiler feed line shut-off, cooling tower bypass.
  • Irrigation & Agriculture:​ Main line solenoid shut-off for large-area sprinkler systems.
  • Industrial Process:​ Compressed air main isolation, coolant flow control, detergent dosing (with FKM seals).
  • Washdown & CIP:​ With EPDM seals — temperature-rated for clean-in-place rinse cycles (≤90–140°C depending on seal).
Note: The EV220B is pilot-operated and requires minimum 0.3 bar pressure differential​ — it will NOT open on zero differential (tank gravity drain with no backpressure). For zero-minimum-differential (direct lift) at DN40, see Danfoss EV210B​ or EV310B​ series (typically smaller DN). Coil and seal material must be specified at time of order — example complete part: EV220B-40B0400 (body) + 018F6758 (230V AC 8W BF coil) + DIN connector.
