Danfoss 193B-1536 4 Way Valve

The Danfoss 193B-1536 4-Way Valve is a high-performance rotary mixing valve engineered for precision temperature control in hydronic heating and cooling systems. Built with a DZR brass valve body (Dezincification Resistant), this 2-inch valve provides exceptional durability in closed-loop applications using water or up to 50% glycol concentrations. With a significant flow capacity of 46.8 Cv and 2" FNPT threaded connections, it is designed for high-flow installations requiring reliable fluid temperature regulation. This ESBE VRG140 series valve supports a broad operating range, withstanding temperatures from 14°F to 230°F and a maximum working pressure of 145 PSI. For automated performance, it integrates seamlessly with ESBE ARA600 series or Series 90 actuators, allowing for efficient boiler protection or outdoor reset control. The low internal leakage rate and visible position indicator ensure long-term operational accuracy in demanding commercial and residential HVACR environments.

• Durable Construction: The DZR brass body prevents corrosion and ensures longevity in various water qualities.
• High Flow Efficiency: A 46.8 Cv rating allows for high-volume throughput with minimal pressure drop across the 2" 4-way mixing valve.
• Flexible Actuation: Compatible with ESBE 90 series actuators for precise, automated hydronic temperature control.
• Wide Operating Envelope: Rated for temperatures up to 230°F, making it suitable for both chilled water and high-temp heating loops.

• What actuators are compatible with the Danfoss 193B-1536? This valve is designed to work with ESBE ARA600 and Series 90 electronic motor actuators for automated mixing and diverting.
• Can this valve be used in cooling applications? Yes, the Danfoss 193B-1536 is rated for fluid temperatures as low as 14°F, making it ideal for chilled water systems.
• How does a 4-way valve differ from a 3-way valve in this application? A 4-way valve provides an additional port, typically used to provide boiler protection by ensuring a minimum return temperature while simultaneously managing the loop temperature.
