COMPETITIVE ADVANTAGES
ARFLU Knife gate valves are engineered and built to handle extreme working conditions for abrasive fluids and high pressure services.
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.
DESIGN FEATURES
FERTILIZERS INDUSTRY
The nature of the knife gate valve and its ability to utilize high alloys such as Super Duplex and/or SS904L for its wetted metallic components (body & sliding knife) enables a properly designed knife gate valve to master the role of the suction and discharge isolation valves on the filter feed pumps, providing the most economical and operationally successful solution.
MINING AND MINERALS PROCESSING
The Mining and mineral processing Industry has hundreds of different critical processes, from the grinding circuit through to the refined or smelted products, that require reliable and cost-effective engineered valve solutions. ARFLU Knife gate valves are engineered and built to handle extreme working conditions for abrasive fluids and high pressure services.
POWER GENERATION
Plant availability can be affected by unplanned downtime, unpredictable power generation, high maintenance costs, and adherence to changing environmental and safety regulatory requirements. ARFLU Knife gate valves solutions are flexible and can be specially-made to fit customer needs.
PULP AND PAPER
Finding innovative ways of increasing production yields while lowering operating costs is mandatory to succeed in the pulp and paper applications. Our Knife gate valves are the ideal solution for the pulp and paper industry.
WATER TREATMENT
Valves for waste water applications require an excelent flow characteristic and be able to withstand the media settling. KNIFE GATE VALVE type push-though knife gate valves incorporates unique design features to provide a reliable operation able to cut through difficult dry media.
