Danfoss 065B-6200 Valve

The Danfoss 065B-6200 is a 4-inch flanged 4-way rotary valve engineered for precision temperature regulation in high-capacity hydronic and HVAC systems. As a heavy-duty HFE 4 PN6 100/225 configuration, this ESBE 4-way valve is constructed with a robust cast iron body and an EPDM seat, supporting a high flow coefficient of 265 Cv. Designed for both mixing and diverting applications, it maintains system efficiency in large-scale commercial and industrial boiler circuits. This rotary flange valve operates reliably within a wide temperature range of 14°F to 230°F (-10°C to 110°C) and handles a maximum static pressure of 90 psi (6 bar). For automated control, it is fully compatible with Danfoss AMB 162/182 series actuators or ESBE Series 90 motors. The dual-sided scale on the faceplate allows for versatile mounting positions, ensuring a seamless fit for complex field piping layouts while providing the double-mixing performance essential for protecting heat sources from low return temperatures.

• High Flow Performance: Boasts a 265 Cv valve rating to handle demanding flow rates in 4-inch flanged pipe systems.
• Double Mixing Function: Optimizes boiler return temperatures to reduce the risk of condensation and thermal shock in the heat exchanger.
• Durable Construction: Cast iron frame with HFE 4 PN6 100/225 specs ensures longevity in closed-loop hydronic heating and cooling applications.
• Actuator Compatibility: Easily pairs with Danfoss HVAC valve actuators like the AMB series or ESBE 90 controllers for 3-point or modulating control.
• Flexible Installation: Features a flanged PN 6 connection and a reversible faceplate for easier integration into various piping configurations.

Is this valve compatible with glycol mixtures?
Yes, the 065B-6200 is suitable for use with 100% water or water-glycol mixtures up to a 50% concentration in closed-loop systems.

What is the maximum operating pressure for this 4-way rotary valve?
This industrial control valve is rated for a maximum static pressure of 6 bar (90 psi) and a maximum differential pressure drop of 50 kPa.

Does this valve come with gaskets and flanges?
Typically, the valve body is sold separately; please verify if your installation requires additional PN-6 flange gaskets or mounting kits for the specific actuator you are utilizing.
