Danfoss EV220B 15 Normally Open Solenoid Valve | G 1/2 | 032U7180

Product Description: The EV220B (032U7180) is engineered for durability and reliability in demanding Middle Eastern environments. In the UAE—where water management and industrial cooling are vital—this valve’s “Normally Open” function ensures that the valve remains open when de-energized, making it ideal for safety systems or cooling loops that must remain active during power failures. With a $G\ 1/2$ connection and a $K_v$ value of $4.0\ m^3/h$, it offers high flow capacity. Its brass body and EPDM sealing (standard for NB/EPDM) provide excellent resistance to the high temperatures and water chemistry often encountered in Dubai and Abu Dhabi’s utility networks.

Key Features & Benefits:

• Normally Open (NO) Function: Ensures flow continues when the coil is de-energized, a critical fail-safe for many UAE industrial processes.
• Built-in Pilot Filter: Protects the pilot system from impurities, reducing maintenance needs in areas with varying water quality.
• Water Hammer Damping: Specifically designed to close smoothly, protecting pipes from the destructive forces of water hammer common in high-pressure UAE buildings.
• High Flow Capacity: The $K_v$ value of $4.0\ m^3/h$ ensures efficient fluid delivery for medium-sized pipelines.
• Versatile Application: Suitable for water, oil, and neutral media with temperatures up to 120°C (depending on seal and coil type).

FAQs:

• Q: Why use a Normally Open valve (032U7180) in the UAE?
• A: It is used in systems where flow is the “safe” state or where the valve only needs to be closed occasionally (e.g., a bypass line or safety cooling), saving energy on coil activation.
• Q: Is the coil included with the 032U7180?
• A: This code usually refers to the valve body. In the UAE, you would typically pair this with a Danfoss BB or BE coil (24V or 220V) depending on your site’s electrical requirements.
• Q: Can this valve be used for steam in Dubai?
• A: No, while the EPDM seals handle hot water, for steam applications in the UAE, you should look at the EV225B or EV215B series.
