Danfoss 193B-1533 Brass Valve

The Danfoss 193B-1533 is a robust 1-inch FNPT 4-way brass valve designed for precision fluid control in hydronic heating and cooling systems. Engineered for high-demand commercial environments, this Danfoss mixing valve features an 11.7 Cv flow coefficient, ensuring consistent performance under varied pressure drops. Rated for 145 PSI (10 bar) maximum pressure, the 193B1533 provides reliable flow diversion and mixing, making it a staple for technicians managing multi-zone temperature regulation. Its high-grade brass construction resists dezincification and corrosion, extending the service life of the mechanical assembly in closed-loop systems. This valve serves as a direct drop-in replacement for legacy 193B1533 units, maintaining the exact face-to-face dimensions required for fast field retrofits. Whether you are balancing a primary-secondary loop or managing radiant floor headers, the linear flow characteristics of this 4-way seat ensure stable hydraulic performance without the hunting associated with lower-quality alternatives.

• High Flow Efficiency: The 11.7 Cv rating minimizes system pressure drop, allowing for smaller pump head requirements and reduced energy consumption.
• Durable Brass Forging: Built to withstand commercial mechanical room conditions and high-temperature fluid cycles without structural degradation.
• Versatile Porting: The 4-way configuration allows for simultaneous control of supply and return flows, simplifying complex hydronic piping layouts.
• Standardized Threading: 1" FNPT connections ensure compatibility with standard domestic and commercial piping without the need for specialized adapters.

What is the maximum operating temperature for the Danfoss 193B-1533?
This 4-way brass valve is typically rated for fluid temperatures ranging from 35°F to 230°F, depending on the specific actuator and seal combination used in the assembly.

Can this valve be used for both mixing and diverting applications?
Yes, the internal porting of the 4-way brass valve allows it to function effectively in both mixing and diverting configurations within a hydronic circuit.

Is the 193B1533 compatible with glycol-based systems?
The brass body and internal components are compatible with water and water-glycol mixtures up to a 50% concentration, standard for most HVACR applications.
