End-of-line armature, as breather and venting device, mainly used for tanks in which inflammable liquids are stored.
Used to prevent inadmissible pressure or vacuum as well as gas losses or inadmissible emissions respectively.
Valve is not explosion-proof on endurance-burning proof.

KITO® VD/o-1

Application:

End-of-line armature, as breather and venting device, mainly used for tanks in which inflammable liquids are stored.
Used to prevent inadmissible pressure or vacuum as well as gas losses or inadmissible emissions respectively.
Valve is not explosion-proof on endurance-burning proof.

KITO® VD/o DN 25

Application:

As end-of-line armature, as venting and breather device mainly for tanks in which incombustible liquids are stored.
Valve is used to prevent inadmissible pressure or vacuum as well as gas losses or inadmissible emissions respectively
Valve is not explosion-proof or endurance-burning proof.

KITO® VD/oP

Application:

As end-of-line armature on storage tanks and silos in which powder products and granulates are stored.
Used as venting and breather device to prevent inadmissible pressure or vacuum.
All moving parts are outside the storage room.

KITO® VD/oL
