Danfoss EV220B 25 Normally Open Solenoid Valve | G 1 | 032U7182

Product Description: The EV220B (032U7182) is built to handle high flow rates with its large 25mm orifice (DN 25). In the UAE—where efficient water distribution and irrigation are essential—this valve’s “Normally Open” design ensures that fluid continues to flow when the coil is de-energized. This makes it an ideal choice for cooling systems, safety circuits, or any application where the valve must remain open by default. The valve is equipped with a built-in pilot filter to ensure longevity in systems where water quality may vary, and its specialized diaphragm design helps mitigate water hammer, protecting the extensive piping networks found in Dubai’s high-rise buildings and Abu Dhabi’s industrial zones.

Key Features & Benefits:

• Normally Open (NO) Function: The valve stays open without electrical power, providing a fail-safe flow for critical cooling or drainage applications in the UAE.
• Large Flow Capacity: With a $K_v$ value of $11.0\ m^3/h$, it is suitable for high-volume liquid and gas transfer.
• Integrated Pilot Filter: Minimizes the risk of debris clogging the pilot orifice, reducing maintenance frequency in dusty Middle Eastern environments.
• Damped Closing: Engineered to prevent pressure surges (water hammer), ensuring the structural integrity of connected pipework.
• EPDM Sealing (NB): Specifically chosen for its excellent performance with water and neutral liquids at temperatures up to 120°C.

FAQs:

• Q: Is this valve compatible with the standard 220V coils available in the UAE?
• A: Yes, while the 032U7182 is the valve body, it is designed to be used with the Danfoss Clip-on coil system (Type BB, BE, or BG) commonly stocked in Dubai.
• Q: Can I use this for compressed air systems in Sharjah?
• A: Yes, the EV220B series with EPDM seals is excellent for compressed air, provided the air is oil-free.
• Q: Does it require a minimum pressure to operate?
• A: Yes, being a servo-operated valve, it requires a minimum differential pressure of 0.3 bar to open and close correctly.
