Product Overview
The Siemens VVI41.25-10 is a 2-port threaded control valve engineered for precise regulation of fluid flow in industrial process and HVAC hydraulic systems. As part of Siemens’ proven VVI41 series, this valve utilizes a pressure-independent, externally threaded globe valve body with a linear characterized plug, delivering accurate flow control proportional to the actuator stroke. The VVI41.25-10 is designed for use with Siemens electromagnetic actuators (or compatible third-party actuators) and serves as a modulating control element in closed-loop water and glycol circuits. Its robust brass construction and threaded connections ensure reliable, leak-free performance in demanding industrial environments, making it a trusted component for temperature, pressure, and flow regulation in building automation and process engineering.
