STRUCTURE AND FUNCTION

The electromotive valve consists of an electromotive linear actuator,
a swivel plate and a 2/2 way globe valve body or a 2/2 way angle
seat valve body.
Valve seat:
The valve seat is always closed against the medium flow so the
flow direction must be determined such that the valve reaches
the flow under the seat.
