Product Overview
The Siemens VXF43.80-100 is a high-performance 3-port flanged control valve engineered for precise regulation of flow in industrial process and HVAC hydraulics. As part of Siemens’ proven VXF43 series, this valve operates as a mixing or diverting control element, allowing accurate modulation of fluid streams in response to actuator commands. With a nominal size of DN80 and a flow coefficient (kvs) of 100 m³/h, it is designed for demanding closed-loop control tasks where stable, repeatable performance is essential. The valve body is constructed from robust materials suitable for water and neutral media, making it a reliable component in district heating, cooling circuits, and general process control systems.
