Abstract
The gate valve has a slider (10) with an aperture (11), located inside a housing (1) and operated by two sliding shafts (13) linked to a servo-drive (14). seals separate the outside from the housing and allow the shafts to slide into the housing. The couplings between the shafts and the slider are tapered to prevent fouling by the flow medium. The drive shafts have sloping faces on the couplings and grip the gate element via pivot bolts on a tapering profile. The shape of the coupling allows full flexibility without affecting the action of the valve.
