Product Overview
The Siemens VVG44.32-16 is a 2-port threaded control valve engineered for precise modulation of hot and chilled water, brine, and other non-corrosive media in building automation and industrial process systems. As part of the Siemens VVG44 series, this valve features a robust bronze body with a threaded connection and is designed for use with Siemens electromagnetic actuators (SAX, SKD, SKB, or SKC series) to provide accurate proportional control. The valve operates on a linear or equal-percentage flow characteristic, making it ideal for continuous modulating duty in HVAC and process control loops. Its 2-port configuration allows for precise throttling of flow in response to a 0–10 V or 4–20 mA control signal, ensuring stable temperature and pressure regulation in demanding industrial environments.
