Product informations

Absolutely maintenance free the COMPACT-Cross sealing as double sealing ring profile secures the sealing of the knife gate towards outside and can be post-sealed - without operation interruption

Excellent sealing the knife gate closes pressure-tight in both flow directions, the seat sealing is chambered and built-in, slightly pre-tensioned. The metallic and jitter-free guided knife gate is resistant against pressure impacts through lock closing condition

Universally operational the DOMINO-knife gate is suitable to regulate highly liquid, thick fluid and gasesous media, as well as all transportable solid materials, especially for air.

Secure separation the cutting edge on the lower body surface largely prevents jamming of material rests in the sealing area. The segment-formed radius of the knife gate prevents a clamping effect.

Longevity guaranteed through the high finish of the lateral running and seal surface. Easily moveable even after long standstill intervals

Optimal jitter free bearing of the knife gate in both flow directions and restrictor positions, made possible throuh the lateral plate guidance

variable drive selection Handwheel, square, reduction gearbox, pneumatic cylinder, hydraulic cylinder, electro actuator
