EV222B, Servo-operated 2/2-way solenoid valves with isolating diaphragm - DANFOSS INDUSTRIAL AUTOMATION

Servo-operated 2/2-way solenoid valves with isolating diaphragm, such as the EV222B series from Danfoss Industrial Automation, are precision-engineered components designed for reliable fluid control in demanding industrial environments. These valves utilize a servo-assisted mechanism that leverages differential pressure to achieve efficient switching, even with low power consumption. The isolating diaphragm ensures media separation, protecting the coil and actuator from corrosive or contaminated fluids. Key technical specifications include a wide range of orifice sizes, pressure ratings up to 16 bar, and compatibility with various media like water, air, oils, and neutral gases. The valves are available in normally closed (NC) and normally open (NO) configurations, with body materials such as brass or stainless steel, and seal options like EPDM, NBR, or FKM to suit specific chemical compatibility requirements. Coil voltages range from 24 VDC to 230 VAC, with IP65 protection for harsh environments.

These solenoid valves are integral to automation systems in sectors such as water treatment, HVAC, food and beverage processing, chemical dosing, and industrial washing systems. They are commonly installed in piping networks for precise on/off control of fluids, often integrated into PLC-controlled processes. Their robust design makes them suitable for applications requiring frequent cycling and long service life, such as in irrigation systems, steam control, and compressed air management. The servo-operated principle allows for high flow rates with minimal pressure drop, making them ideal for large-diameter pipelines.

Within this category, the EV222B series is the primary product line, featuring subcategories based on connection size (e.g., G1/2 to G2), function type (NC or NO), and seal material. Key article codes include EV222B 032U5511 (G1/2, NC, EPDM), EV222B 032U5512 (G3/4, NC, NBR), and EV222B 032U5513 (G1, NO, FKM). The code structure typically follows the pattern: EV222B + 3-digit series identifier + 4-digit variant number, where the variant number encodes connection size, seal type, and voltage. Accessories like coil kits (e.g., 018Z6000) and cable plugs are also available.
