STH High Pressure Through Conduit Knife

Through conduit knife gate valves are specially made for the pulp and paper industry, for pulp outlets or under silo applications. The design allows flow media with high consistency either for normal or reverse flow due to the bi-directional double seat design. The high flow coefficient value of this knife gate valve provides high flow rates with low pressure drops. The two-piece construction bolted body retains a gate that contains a round openning inside that is able to cut the flow for the required charged liquid applications. When the opening of the gate is aligned with the opening of the split-bodies, the valve is opened.  The gate closing principle is similar to the functioning of a «cigar cutter».
