Product Overview
The Siemens VXG44.15-0.4 is a 3-port threaded control valve engineered for precise regulation of hot and cold water, brine, and other non-aggressive media in HVAC and industrial process systems. As part of Siemens’ proven VXG44 series, this valve features a robust brass body with a threaded connection design, providing reliable modulating control when paired with Siemens electromagnetic actuators or thermal actuators. The 3-port mixing or diverting configuration allows for accurate flow proportioning between two inlet ports and a common outlet, making it an essential component in district heating, building automation, and industrial temperature control loops. Its compact construction and high-resolution control characteristics ensure stable performance across varying differential pressures.
