The Siemens VVF63.40-20 two-port control valve is a PN 40 flanged valve designed for precise control or shut-off of the medium in boiler houses, chiller plant rooms, cooling towers, heating systems and AHU units. The valve is suitable for both closed and open hydraulic circuits, subject to cavitation being taken into account, and is designed for media with temperatures ranging from -25 to 220 °C. The cast steel body ensures reliable operation even in more demanding applications. The valve has a nominal diameter of DN 40, a Kvs value of 20 m3/h and a flanged connection. It is intended for use in combination with Siemens SKD, SKB and SKC series electric actuators.
