Danfoss EV220B50 Solenoid Valve | 2/2 NC, G3/4, 0-16 bar, 24V AC/DC, IP65 Specs

Danfoss EV220B50 solenoid valve specifications. 2/2-way normally closed, G3/4 port, 0-16 bar pressure, 24V AC/DC, IP65. For water, oil, and neutral media control.

Product Overview

The Danfoss EV220B50​ is a direct-acting solenoid valve​ from the EV series, designed for controlling the flow of water, oil, and neutral media in industrial and commercial applications. This model is a 2/2-way normally closed valve​ with G3/4 threaded ports, operates within a 0-16 bar pressure range, and is available with 24V AC or DC coil. The "EV220B50" designation identifies this specific valve configuration within Danfoss's EV series. This robust solenoid valve provides reliable on/off control for various fluids in heating, cooling, and general industrial applications.

Technical Specifications

Note: Specifications are based on Danfoss EV series technical documentation. The exact "EV220B50" model typically corresponds to a G3/4, 2/2 NC configuration. Some parameters like Kv value and exact dimensions may vary slightly. The coil voltage (24V AC or DC) must be specified as a separate ordering option.

Model Number Decoding (EV220B50)

• EV:​ Series designation (EV solenoid valve series)

• 220:​ Valve type and size code (2/2-way, specific orifice/port size)

• B50:​ Configuration code (B = brass body, 50 = specific variant/port thread)

Note:​ The "EV" prefix indicates the standard solenoid valve series. The numerical code "220" typically denotes a 2/2-way valve with a specific orifice size. The suffix "B50" indicates material (Brass) and connection type (G3/4). The coil voltage is a separate selection.

Key Features

• Direct-Acting Design:​ Operates from zero pressure differential, no minimum pressure required.

• Normally Closed:​ Valve closes when de-energized for fail-safe operation.

• Robust Brass Body:​ Nickel-plated brass for corrosion resistance and durability.

• IP65 Protection:​ Coil is protected against dust and water jets.

• High Pressure Rating:​ Suitable for systems up to 16 bar.

• Wide Media Compatibility:​ Suitable for water, air, light oils, and neutral media.

• Fast Response:​ Quick opening and closing times for precise control.

• Versatile Mounting:​ Can be installed in any position (optimal with coil upright).

• Energy Efficient:​ Low power consumption design.

• Global Approvals:​ Carries major international safety and quality certifications.

Flow Characteristics

Typical Applications

• HVAC Systems:​ Control of heating and cooling water circuits.

• Industrial Automation:​ On/off control of process water, air, or oil lines.

• Water Treatment:​ Control valves for filtration, dosing, or distribution systems.

• Irrigation Systems:​ Control of water supply in agricultural and landscape irrigation.

• Machine Tools:​ Cooling circuit control for machining centers.

• Compressed Air Systems:​ Control of air supply to tools and actuators.

• Boiler Systems:​ Make-up water or circulation control.

• General Plumbing:​ Automated water supply control in commercial buildings.

Important Technical Notes

1. Coil Voltage Specification:​ The valve body (EV220B50) is typically sold separately from the coil. The correct coil (24V AC or 24V DC) must be ordered separately using the appropriate coil reference number.

2. Media Compatibility:​ Ensure the valve seals (standard NBR) are compatible with the fluid media. For specific chemicals or high temperatures, confirm seal material compatibility (EPDM, FKM options may be available).

3. Pressure Rating:​ The 16 bar rating is for the valve body. Ensure all system components (pipes, fittings) are rated for the operating pressure.

4. Installation:​ Install with flow direction according to the arrow on the valve body. A strainer before the valve is recommended for dirty media. Use proper thread sealant (e.g., PTFE tape) on male threads, avoiding entry into the valve orifice.

5. Electrical Connection:​ The coil has a standard DIN connector or lead wires. Ensure the power supply matches the coil specification precisely (24V AC or DC).

6. Minimum/Maximum Temperature:​ Do not exceed the specified media and ambient temperature limits to prevent seal damage or coil failure.

7. Cycling:​ While capable of frequent cycling, for very high cycle applications, consult technical specifications for duty cycle limitations.
