PARAVALVES is committed to provide robust and reliable slurry knife gate valves for the mining and mineral processing industry.
At PARAVALVES, every product is carefully engineered as all the neccesary parameters are studied to develop our solid and reliable slurry knife gate valves.
Slurry knife gate valves are specially made for the mining industry, for loaded fluid lines like sludge or abrasive services. Slurry knife gate valves performs also well for waste water treatment, pulp and paper industry, chemical plants, silo outlet and thermal power plants. 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 main characteristic of the slurry knife gate valve is that it provides a full continuous flow. In open position the two rubber wear-resistant sleeves are in close contact with each other preventing the flow get inside the valve body. Installation of this equipment is done between pipeline flanges, which flange drilling can be made according to customer specifications or PARAVALVES standard.
K|220 SLURRY KNIFE GATE VALVE series are divided in different types depending on the design pressure and face to face values. K|221 model is reffered to standard design with differential pressures up to 10bar depending on valve size (see section below). K|222 model shall be selected for higher design pressures up to CLASS 150#. In case long patter design is required for the application, either K|223 or K|224 models can bet selected providing a long-pattern design with higher face to face.
Different materials are available such as carbon steel or many stainless steel grades according to required application.
DN50 to DN600: 10bar.
DN700 to DN900: 6bar.
DN1000 to DN1400: 4bar.
