1. Water treatment and environmental protection industry
Sewage treatment: Knife gate valves are used to control sewage, sludge and fluids containing suspended matter. Their wear-resistant design can effectively prevent blockage and ensure the stable operation of the treatment system.
Municipal water supply and drainage: In water supply networks, rainwater discharge and fire protection systems, knife gate valves have become key control equipment due to their low flow resistance and easy maintenance.
2. Energy and power industry
Thermal power generation: Used for boiler water supply and drainage, cooling water circulation and ash treatment systems, adapting to high temperature and high pressure environments.
Nuclear power plants and substations: Control the flow of cooling media and chemical additives, requiring high sealing and corrosion resistance.
3. Mining and metallurgical industry
Ore transportation: Handling slurry, tailings and other media containing high concentrations of solid particles, the sharp gate of the knife gate valve can cut impurities and avoid blockage.
Steel smelting: Applied to cooling water system, wastewater treatment and blast furnace gas control, with outstanding high temperature and high pressure resistance.
4. Chemical and petrochemical industry
Corrosive medium control: Used for the cutoff and regulation of dangerous fluids such as acids, alkalis, solvents, etc., stainless steel or special coating materials are required to enhance corrosion resistance.
Pipeline safety isolation: In oil and gas transportation, soft-sealed knife gate valves can prevent leakage and meet explosion-proof requirements.
5. Food and pharmaceutical industry
Sanitary fluid treatment: The knife gate valve’s no-dead-angle design and easy-to-clean characteristics are suitable for scenes with high cleanliness requirements such as dairy products and sauces.
Pharmaceutical process control: Used for liquid medicine transportation and reactor medium isolation, must comply with GMP standards.
6. Papermaking and building materials industry
Pulp treatment: The knife gate valve can cut off viscous fluids such as high-concentration wood pulp and black liquor, and has strong anti-fouling ability.
Concrete and building materials production: used for flow control of cement slurry and aggregate conveying systems, with excellent wear resistance.
7. Other emerging fields
New energy: such as ash treatment systems in biomass power generation.
Environmental protection engineering: leachate control in urban waste treatment plants.
