Siemens electric valve

Siemens electric control valve VVF42C series

Two way and three-way valves PN 16, flange connection

VVF42. C., VVF42.. KC, VXF42. C. belong to the long stroke valve series and are used for chilled water, low-temperature water, high-temperature water, and saltwater.

Valves with medium temperature ranging from -10 to 150 ℃

The valve body is made of gray cast iron EN-GJL-250 or above

DN 25…150

k vs 6.3…400 m 3 /h

Flange type 21, flange design is B

VVF42..KC， Equipped with pressure compensation function, suitable for high pressure differential applications, it can be equipped with electric actuators SAX. or electric hydraulic actuators SKD., SKB., SKC

Application:

As a regulating or shut-off valve, it is used in boilers, central heating and cooling equipment, cooling towers, heating equipment, ventilation and air handling units.

VVF42. C., VXF42. C. are used for closed systems (pay attention to cavitation phenomenon).

VVF42.. KC is used for closed or open systems (pay attention to cavitation phenomenon).

technical design：

Mechanical design may have different structural features, such as the shape of valve plugs. VVF42.. KC valve adopts pressure compensation plug. This can be used to control high pressure differentials with actuators of the same model.

Caution: Do not turn a two-way valve into a three-way valve by removing the blind flange!
