Danfoss 032U6533 Solenoid Valve

The Danfoss 032U6533 solenoid valve is a robust 3/4 inch NPT indirect servo-operated 2/2-way solenoid valve specifically engineered for neutral media including water, brine, and compressed air. Part of the proven EV220B series, this model—also recognized as 032U-6533—delivers a substantial 9.4 Cv flow coefficient, ensuring efficient fluid management in high-demand HVACR and industrial service environments. The heavy-duty brass body construction and EPDM seal material provide reliable performance across a broad medium temperature range from -22°F to 248°F. A critical feature for contractors is the soft close function, which utilizes a damped diaphragm design to effectively eliminate water hammer and protect the integrity of the downstream piping. This normally closed (NC) valve requires a minimum differential pressure of 4.35 PSI to actuate and can handle a maximum working pressure up to 232 PSI, making it a versatile choice for professional fluid control applications.

Key Benefits:

• Water Hammer Prevention: The integrated soft close dampening system prevents hydraulic shock, extending the life of both the 032U6533 and your piping infrastructure.
• Durable Construction: Features a high-quality brass body and stainless steel internal components for superior corrosion resistance in HVACR systems.
• Debris Protection: Includes a built-in pilot filter as standard to protect the pilot system from particulate matter, reducing maintenance call-backs.
• High Flow Capacity: The 9.4 Cv rating allows for high volume throughput with minimal pressure drop across the 3/4 inch NPT connection.
• Universal Certification: UL listed and compliant with major marine standards (DNVGL), ensuring it meets the most stringent industrial code requirements.

Common Questions:

What media can the Danfoss 032U6533 handle?
This servo-operated solenoid valve is optimized for water, brine, and secondary coolants. The EPDM seals are also suitable for low-pressure steam up to 60 PSI (4 bar).

Does this valve include a coil?
The 032U6533 is typically supplied as the valve body only. Professional installers should match the appropriate Danfoss 13.5mm actuator/coil system (Clip-on or Nut-fixed) to meet their specific voltage requirements.

What is the minimum pressure required for operation?
As an indirect servo-operated valve, it requires a minimum differential pressure of approximately 0.3 bar (4.35 PSI) to open and function correctly.
