Danfoss 193B-1502 3 Way Valve

The Danfoss 193B-1502 is a high-performance 3-way mixing valve engineered for precision flow control in hydronic heating and cooling systems. Constructed from DZR brass (Dezincification Resistant), this valve is specifically designed to withstand aggressive water conditions, preventing premature corrosion and ensuring long-term seat integrity. With a 3/4" NPT external thread connection and a 7.3 CV flow coefficient, it provides the necessary capacity for medium-sized residential and light commercial zone control applications. This rotary valve is optimized for mixing or diverting functions, allowing technicians to maintain stable supply temperatures even under fluctuating load conditions.

For automated operation, the 193B-1502 integrates seamlessly with Danfoss actuators—typically requiring an adapter for specific series—to provide modulating or on/off control. Its compact footprint is ideal for tight mechanical rooms or fan coil unit enclosures. The internal rotary shoe is precision-machined to minimize leakage and bypass, ensuring that your HVAC hydronic system operates at peak thermal efficiency. Whether you are replacing a legacy VRG unit or installing a new mixing loop, this valve provides the reliability required for professional-grade installations.

• DZR Brass Construction: Superior resistance to dezincification, protecting the system against corrosion in various water qualities.
• 7.3 CV Rating: Offers high-capacity flow performance for 3/4" line sizes, reducing pressure drop across the valve body.
• Versatile 3-Way Design: Easily configured for mixing or diverting applications to suit specific piping schematics.
• Rotary Precision: Engineered for smooth operation and tight shut-off, reducing hunting in modulating control loops.

What actuators are compatible with the 193B-1502?
This valve is part of the ESBE/Danfoss rotary series. It is commonly paired with AMV or AME series actuators, though a specific mounting kit (such as the 065Z0311) may be required depending on the actuator generation.

Can this valve be used for potable water?
The DZR brass construction makes it highly resistant to corrosion; however, technicians should verify local plumbing codes regarding lead-free requirements for domestic hot water applications.

Is this valve suitable for both heating and chilled water?
Yes, the 193B-1502 is designed to handle a wide temperature range, making it suitable for boiler mixing loops as well as chilled water air handling applications.
