Siemens VBF21.100 3-Way Rotary Valve DN100
Precise, energy-efficient flow diversion for large-scale building services.
Siemens VBF21.100 3-Way Rotary Valve DN100 delivers energy-efficient and precise liquid routing in large-scale facilities. In addition, its DN100 flanged connection and 160 m³/h Kvs value provide outstanding performance in high-flow heating and cooling circuits. Moreover, the cast iron body offers excellent resistance to corrosion.
This valve operates in both mixing and diverting modes, which makes it indispensable for automation systems. Furthermore, its EPDM sealing material reduces energy losses through a minimum leakage rate. In particular, the 90° rotation angle enables fast and precise flow diversion. As a result, it integrates easily into building automation when paired with Siemens SAX, SKD, and SKB series actuators. Maximum working temperature is 120°C.
