Product Overview
The Siemens VAF41.100-160 (S55232-V107) is a 2-port flanged control valve engineered for precise regulation of flow in industrial process and building technology systems. As part of Siemens’ VAF41 series, this valve features a robust cast iron or ductile iron body with a flanged connection interface, designed for modulating control of water, steam, and compatible non-aggressive media. The valve operates with a linear or equal-percentage characteristic, enabling accurate temperature, pressure, or flow control when paired with Siemens actuators (e.g., SAX, SKD, or SQL series). Its 2-port configuration provides bidirectional shutoff capability, making it suitable for both mixing and diverting applications in closed-loop hydronic circuits. The model designation “100-160” indicates a nominal diameter of DN100 with a flow coefficient (kvs) of 160 m³/h, ensuring high capacity for medium-to-large industrial process lines.
