Product Overview
The Siemens VXF42.150-315C (S55204-V180) is a high-performance 3-port flanged control valve engineered for precise regulation of hot water, chilled water, and steam in building automation and industrial process systems. As part of Siemens’ VXF42 series, this valve features a robust cast iron or ductile iron body with a flanged connection, designed for mixing or diverting service in closed-loop hydronic circuits. The VXF42.150-315C is typically paired with Siemens electro-hydraulic or magnetic actuators (e.g., SKD, SKB, or SQL series) to provide accurate modulating control, ensuring stable temperature and flow regulation in demanding HVAC and process applications. Its 3-port configuration allows for either mixing (two inlets, one outlet) or diverting (one inlet, two outlets) operation, making it a versatile component in district heating, cooling, and industrial fluid control systems.
