Danfoss 032U1251 Solenoid Valve

The Danfoss 032U1251 is a high-performance EV220B 15 series solenoid valve designed for robust fluid control in demanding HVACR and industrial applications. This 1/2" G threaded, 2/2-way normally closed (NC) valve utilizes a servo-operated diaphragm design, requiring a minimum differential pressure of 0.3 bar for reliable actuation. Constructed with a durable brass body and EPDM sealing material, it is engineered for compatibility with water, glycol, and similar neutral media across a broad temperature range of -30°C to 120°C. This valve is a direct replacement solenoid valve for systems requiring precise flow regulation and long-term cycle reliability. The internal damping system effectively minimizes water hammer, protecting downstream piping and components from pressure surges. Designed for use with Danfoss clip-on coils (sold separately), the 032U1251 ensures a secure, tool-free electrical connection, streamlining field installation and maintenance for service technicians.

Technical Specifications and Benefits:

• Broad Media Compatibility: Optimized for water and glycol-based cooling circuits.
• Pressure Range Efficiency: Operates effectively within 0.3 to 16 bar differential pressure.
• EPDM Seal Integrity: Provides superior resistance to heat and chemical degradation in closed-loop systems.
• Reduced Water Hammer: Incorporates a built-in pilot orifice to soften closing transitions.
• Universal Coil Compatibility: Fits standard Danfoss AM and BM series coils for versatile voltage configurations.

Common Questions:

What is the flow capacity (Kv value) of the Danfoss 032U1251?
This model features a 15mm orifice providing a Kv value of 4 m³/h, ensuring high flow rates with minimal pressure drop across the valve body.

Can this valve be mounted in any orientation?
For optimal performance and to prevent debris accumulation in the pilot system, it is recommended to install the valve with the coil in a vertical position, though horizontal mounting is permissible.

Is the coil included with the 032U1251 valve body?
No, this is the valve body assemby only. You must select a compatible Danfoss clip-on coil based on your specific voltage requirements (e.g., 24V, 110V, or 230V AC/DC).
