Danfoss 032U6537 Solenoid valve

The Danfoss 032U6537 EV220B 50 is a high-capacity, 2-inch NPT solenoid valve designed for demanding commercial and industrial fluid handling. This indirect servo-operated valve features a normally closed (NC) configuration and is engineered with soft-close technology to mitigate water hammer, protecting downstream piping and components from pressure surges. With a flow coefficient (Cv) of 46.8, it provides high-volume throughput for water, oil, and compressed air applications. The EPDM seal ensures reliable performance across a broad temperature range, while the brass body provides the structural integrity required for high-cycle installations. This 2-way solenoid valve requires a minimum differential pressure to operate and is compatible with various Danfoss clip-on coils, allowing for flexible electrical integration in the field. When replacing large-bore valves, the 032U6537 offers a field-proven solution for precise fluid control in HVAC and process cooling systems.

Key Benefits

• Reduced Water Hammer: Internal pilot design and soft-close functionality prevent damaging hydraulic shocks in large-diameter piping.
• High Flow Efficiency: A 46.8 Cv rating ensures minimal pressure drop across the valve in high-demand fluid circuits.
• Durable Construction: Built with high-grade brass and EPDM elastomer seals for long-term reliability in varying environmental conditions.
• Versatile Compatibility: Fits standard 2" NPT connections and utilizes the versatile Danfoss coil system for easy maintenance.

Common Questions

What is the minimum pressure differential required for this valve?
As an indirect-operated valve, the 032U6537 typically requires a minimum differential pressure (often 0.3 bar or 4.35 psi) to lift the diaphragm and ensure full flow capacity.

Can this valve be used for steam applications?
While the EPDM seals are excellent for hot water and air, this specific model is optimized for fluid temperatures within the standard EPDM range; for high-pressure steam, always verify the specific media compatibility and temperature limits.

Does this valve include the solenoid coil?
Usually, the Danfoss EV220B series is sold as a valve body and diaphragm assembly. Technicians should verify the required voltage (e.g., 24V or 120V) and source the appropriate clip-on coil separately.
