Product Overview
The Siemens VVF42.65-63C (S55204-V156) is a 2-port flanged control valve engineered for precise modulation of flow in hydronic heating, cooling, and industrial process systems. As part of Siemens’ VVF42 series, this valve features a robust cast iron or ductile iron body with a linear or equal-percentage characterized plug, providing accurate flow control across a wide range of operating conditions. The valve is designed for use with Siemens electromagnetic actuators (such as the SKD, SKB, or SKC series) and is suitable for both open and closed-loop control applications. Its flanged connection ensures secure, leak-free installation in high-flow industrial pipelines, making it a reliable component for demanding process and pneumatic valve applications.
