Product Overview
The Siemens VXG44.40-25 is a three-port seat valve engineered for precise control of hot and cold water, brine, and other neutral media in industrial heating, ventilation, and process systems. As part of Siemens’ proven VXG44 series, this valve features a robust seat-type design with a 40 mm nominal size and a 25 mm stroke, delivering reliable shut-off and modulating control performance. The three-port configuration allows for mixing or diverting service, making it a versatile component for hydronic balancing, temperature regulation, and flow control in demanding building automation and industrial process environments. Its bronze body and stainless steel trim ensure long service life and resistance to corrosion, while the standardized actuator interface enables seamless integration with Siemens magnetic and electro-mechanical actuators.
