STRUCTURE AND FUNCTION

The electromotive control valve consists of an electromotive linear
actuator, a control cone and a 2-way globe valve body or a 2-way
angle seat valve body.
• The flow direction is always below the valve seat.
Valve seats:
• For a globe control valve, the valve seat is screwed-in. The
seat size can easily be reduced by exchanging the screwed-in
valve seat.
• For an angle seat control valve, the valve seat is screwed in the
valve body. This means the seat size cannot be reduced.
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.
