PRODUCT DESCRIPTION
SIEMENS VXG44.15-4 - 3-Port Threaded Mixing/Diverting Valve
This SIEMENS VXG44.15-4 is a 3-port threaded valve engineered for precise mixing or diverting control within hydronic systems. It is designed for integration into heating, ventilation, and air conditioning (HVAC) applications, facilitating flow regulation in closed circuits. The valve operates mechanically, requiring an external electro-motoric or electro-hydraulic actuator for modulation.
