Danfoss EV220B 40 Normally Closed Solenoid Valve | G 1 1/2 | 032U7174

Product Description: The EV220B (032U7174) is built to handle significant fluid volumes with its DN 40 orifice. In the UAE—where cooling towers, large-scale irrigation, and industrial processing require robust flow control—this valve provides a reliable $K_v$ flow capacity of $24\ m^3/h$. The “Normally Closed” design ensures that the valve remains shut when de-energized, providing a secure fail-safe for water supply lines. Designed for long-term durability in the Middle Eastern climate, it features a built-in pilot filter to prevent clogging and a specialized diaphragm design that minimizes water hammer, protecting the extensive piping networks found in Dubai and Abu Dhabi.

Key Features & Benefits:

• High Flow Performance: With a $K_v$ of $24\ m^3/h$, it is optimized for large-scale liquid and gas distribution in UAE facilities.
• Normally Closed (NC) Safety: Provides a tight, automatic shut-off during power loss, essential for preventing floods or process overflows.
• Water Hammer Damping: Engineered for a soft closing action, significantly reducing the risk of pipe damage in high-pressure UAE buildings.
• EPDM Sealing (NB): Suitable for water and neutral liquids at temperatures up to 120°C, making it ideal for both domestic and industrial hot water systems.
• Rugged Brass Construction: Offers the mechanical strength needed for industrial environments and high-ambient temperature machine rooms.

FAQs:

• Q: Is the 032U7174 suitable for high-rise water booster stations in Dubai?
• A: Yes, its 1 1/2-inch port and high flow capacity make it a standard choice for booster pump sets and main distribution lines.
• Q: Does this valve require a minimum pressure to operate?
• A: Yes, as a servo-operated valve, it requires a minimum differential pressure of 0.3 bar to lift the large diaphragm and ensure full flow.
• Q: Can I use this for diesel oil in UAE industrial generators?
• A: No, EPDM seals (NB) are not oil-resistant. For diesel or oil applications, you must use the FKM (Viton) version of the EV220B.
