Incoming flow under seat
The valve is closed against the medium flow by spring force
(control function A, CFA) or by control pressure (control function B,
CFB). As the medium pressure is under the seat seal, this pressure
contributes to opening of the valve.
note!
Seat seal or diaphragm subject to wear.
When the incoming flow is over the seat, powerful water
hammers may occur, especially in the case of liquid media.
▶
Do not use device for incoming flow over the seat.
▶
Observe arrow for direction of flow on the valve body.
