Danfoss EV225B Solenoid Valve Body | 2/2 NC, G1, 0-16 bar, 110°C, Brass Body Specs

Danfoss EV225B solenoid valve body specifications. 2/2-way normally closed, G1 port, 0-16 bar pressure, brass body, -10 to 110°C. For water, oil, and neutral media.

Product Overview

The Danfoss EV225B​ is a direct-acting solenoid valve body​ 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 body​ with G1 (1-inch) BSPP threaded ports, operates within a 0-16 bar pressure range, and can handle media temperatures up to 110°C. The "EV225B" designation identifies this specific valve body configuration. This component requires a separate coil assembly for operation and provides the mechanical base for reliable on/off flow control in heating, cooling, and general industrial fluid systems.

Technical Specifications

Note: Specifications are based on Danfoss EV series technical documentation. The "EV225B" model refers specifically to the valve body. A compatible solenoid coil (available in various AC/DC voltages) must be ordered separately. Exact Kv value and dimensions may vary slightly.

Model Number Decoding (EV225B)

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

• 225:​ Valve type and size code (2/2-way, G1 port size)

• B:​ Material code (B = Brass body)

Note:​ The "EV" prefix indicates the standard solenoid valve series. The numerical code "225" typically denotes a 2/2-way valve with G1 port size. The suffix "B" indicates a Brass body. This is a valve body only and requires a compatible EV-series coil for operation.

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.

• G1 Port Size:​ 1-inch BSPP female ports for larger flow applications.

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

• High Flow Capacity:​ Designed for applications requiring higher flow rates (Kv ~9.0).

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

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

• Separate Coil System:​ Coil can be replaced independently without changing the valve body.

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

Flow Characteristics

Typical Applications

• HVAC Systems:​ Control of main heating/cooling water lines, boiler feed.

• Industrial Process Lines:​ On/off control for larger water, air, or oil supply lines.

• Water Distribution:​ Control valves for larger irrigation or water supply systems.

• Tank Filling/Draining:​ Automated control for larger tanks and vessels.

• Compressed Air Mains:​ Control of air supply to larger tools or systems.

• Cooling Systems:​ Main circuit control for industrial chillers or cooling towers.

• General Industrial Plumbing:​ Automated water supply control in industrial facilities.

Important Technical Notes

1. Incomplete Assembly:​ The EV225B is a valve body only. A compatible solenoid coil (e.g., 24V AC, 110V AC, 24V DC) must be ordered separately using the appropriate Danfoss coil reference number.

2. Media Compatibility:​ Standard seal material is NBR (Nitrile). Verify compatibility with the specific fluid media. Alternative seal materials (EPDM, FKM) may be available for different media or temperatures.

3. Pressure Rating:​ Do not exceed 16 bar working pressure. The valve is suitable for zero differential pressure applications.

4. Installation:​ Install with flow direction according to the arrow on the valve body. For dirty media, install a strainer upstream. Use appropriate thread sealant on male connections, ensuring it does not enter the valve orifice.

5. Coil Selection:​ Select a coil with the correct voltage, frequency (for AC), protection rating (typically IP65), and duty cycle (continuous) for your application. Ensure the coil is compatible with the EV225B body.

6. Electrical Connection:​ The coil will have either a DIN connector or lead wires. Follow the coil's wiring instructions precisely.

7. Temperature Limits:​ Do not exceed the specified media and ambient temperature limits. High temperatures can damage seals and coil insulation.

Note: This data sheet provides specifications for the Danfoss EV225B solenoid valve body. For complete technical data, installation instructions, coil selection guide, and material compatibility information, consult the official Danfoss EV Series Technical Documentation. Always verify that the complete assembly (body + selected coil) meets all application requirements.
