Danfoss 193B-1503 Valve

The Danfoss 193B-1503 is a high-performance 1" 3-way DZR brass mixing valve from the ESBE VRG130 series, engineered for precise temperature control in hydronic heating and chilled water applications. Featuring a 7.3 Cv flow capacity, this rotary valve is constructed from Dezincification Resistant (DZR) brass, ensuring long-term reliability in closed-loop systems with up to 50% glycol concentration. Designed to replace legacy MG and G series components, the Danfoss 193B-1503 valve offers an exceptionally low internal leakage rate and a compact footprint that simplifies field piping layout in tight mechanical rooms.

This ESBE VRG130 mixing valve is a versatile solution for both mixing and diverting functions, supporting a temperature range of 14°F to 230°F and a maximum working pressure of 145 psi. For automated performance, it integrates seamlessly with ARA600 series electronic motor actuators and Series 90 controllers, making it an ideal choice for outdoor reset and DDC-controlled HVACR systems. The 1" FNPT threaded connections provide a secure, industry-standard fit for professional contractors requiring robust hydronic mixing valve performance.

Key Benefits

• DZR Brass Construction: High-grade dezincification-resistant material prevents corrosion in demanding hydronic environments.
• Low Leakage Design: Features an industry-leading internal leakage rate (less than 0.05% of flow) to maximize system efficiency.
• Broad Compatibility: Easily pairs with Danfoss rotary actuators like the ARA661 or ARA663 for centralized automation.
• Flexible Installation: Compact rotary design allows for multiple piping orientations and includes a visible position indicator knob.
• High Temperature Range: Rated for fluid temperatures up to 230°F, suitable for high-temp boiler loops and solar thermal applications.

Common Questions

Can the 193B-1503 be used for both mixing and diverting?
Yes, the VRG130 series internal geometry allows for either mixing two inlets or diverting a single inlet to two outlets depending on the piping configuration.

What is the difference between this and the legacy Danfoss MG series?
The 193B-1503 serves as a direct upgrade to the MG series, offering a more compact profile and higher resistance to dezincification while maintaining common Cv ratings.

Does this valve require a specific mounting kit for actuators?
While designed for manual operation with the included knob, it requires a standard mounting kit when being coupled with ESBE ARA600 or Series 90 actuators.
