Siemens VBF21.80 3-Way Rotary Valve DN80
Precise flow management for energy-efficient heating and cooling circuits.
The Siemens VBF21.80 3-Way Rotary Valve DN80 is the ideal choice for energy-efficient flow management in heating and cooling circuits. In addition, it delivers precise flow control and energy efficiency in HVAC systems. Moreover, a DN80 flanged connection and PN6 pressure class suit high-capacity applications.
The cast iron GG25 body offers superior resistance to corrosion. Furthermore, a Kvs value of 100 m³/h delivers effective performance in large-volume systems. This rotary valve operates smoothly at a working temperature of 1°C to 120°C. In addition, a stainless steel stem and a sealing class according to DIN EN 1349 ensure long service life. Consequently, full compatibility with SAX, SKD, and SKB series actuators brings easy installation. Therefore, it combines mixing and diverting functions in a single valve and simplifies system design.
