Oil-Free Chiller Valve

Recently, Danfoss launched the new OFB series shut-off ball valves, designed specifically for oil-free chillers and heat pump systems that incorporate Turbocor® compressors.   The OFB series provides a higher level of operational protection for oil-free systems, especially for applications in data centers and high-end HVAC (Heating, Ventilation, and Air Conditioning) systems. This valve focuses on enhancing the reliability of the suction side and features an innovative "three-in-one" integrated design. According to Danfoss, it combines the suction conical transition section, tight shut-off function, and fully automated control capability into a single unit, significantly simplifying system layout and improving overall performance.     The new OFB series uses a fully modular structure, seamlessly compatible with all Danfoss Turbocor® TGx and TTx compressors. The product offers 12 different inlet flange specifications (including 3-inch, 4-inch, and 5-inch), making it suitable for both new projects and upgrades to existing systems. Additionally, the series supports various international connection standards such as ANSI, ASTM, DIN, and EN, ensuring installation flexibility worldwide.   Thanks to its robust and reliable structural design, the OFB valve operates stably in a wide temperature range of –40°F to +212°F (approximately –40°C to +100°C). Whether in cold or high-temperature environments, it ensures long-term, reliable, and efficient operation of the system.   The product's performance features are as follows:   High-Cycle Design of Stem and Seat for Excellent Reliability:   Strong and reliable sealing performance   Tight shut-off ball valve structure   Low torque design extends the life of the valve and actuator   Modular Flange System Compatible with Various Piping Standards for Easy Integration and Installation:   Welding and brazing connections for standard pipes and elbows   Can be directly equipped with actuators – in accordance with ISO 5211-F07/17 mm standards. After the actuator is installed, it allows for electric control.   Achieves High System Efficiency through Smooth Air Intake Flow, Low Pressure Drop, and Low Fluid Turbulence:   Efficient design: Directly mounted on compressors   Low torque requirement – an 80Nm rated torque 90° actuator is sufficient, extending the service life.
