The Siemens VXI46.20/2 three-port control valve is designed for 2-point (ON/OFF) control in ventilation, air-conditioning and heating systems. It is primarily used for controlling terminal units on the water side in closed circuits, for example fan coil units, induction units, small heaters and coolers.
The valve is designed as a three-port diverting valve with a brass body, Rp internal thread and an M30 x 1.5 actuator connection. It is suitable for hot water, chilled water, or water with anti-freeze additives. For correct and reliable operation, the flow direction AB → A and AB → B must be observed, and installation of a strainer upstream of the valve is recommended.
