The global Knife Gate Valves Market is witnessing steady growth as industries increasingly require reliable flow-control solutions for handling liquids, slurries, powders, and other challenging materials. Knife gate valves are widely used in applications where efficient shutoff and isolation are essential, particularly across water and wastewater treatment, mining, pulp and paper, chemicals, and power generation.
According to Fortune Business Insights, the global knife gate valve market size was valued at USD 1,401.4 million in 2025. The market is projected to grow from USD 1,473.1 million in 2026 to USD 2,239.4 million by 2034, exhibiting a CAGR of 5.3% during the forecast period. Asia Pacific dominated the knife gate valve market with a market share of 38.96% in 2025.
The expansion of industrial infrastructure is a major factor supporting the growth of the Knife Gate Valves Market. Industries that handle abrasive, viscous, or solid-containing fluids require valves capable of providing dependable isolation and flow control under demanding operating conditions.
Knife gate valves are particularly suitable for applications involving slurries and materials that may be difficult to control using conventional valve designs. Their ability to provide effective shutoff makes them useful across several industrial processing environments.
Increasing investments in water infrastructure are creating additional opportunities for knife gate valve manufacturers. Municipalities and industrial facilities are upgrading treatment plants to address growing water consumption, wastewater generation, and environmental requirements.
Knife gate valves are commonly used in water and wastewater applications because they can provide isolation within pipelines and treatment systems. The development of new treatment facilities and modernization of existing infrastructure is expected to support demand during the forecast period.

The Knife Gate Valves Market can be analyzed based on different product configurations, including through-conduit knife gate valves, wafer knife gate valves, lug-style knife gate valves, and other designs.
Different configurations are selected according to operating conditions, pipeline requirements, pressure levels, and the characteristics of the material being handled. Manufacturers are focusing on designs that improve durability, sealing performance, operational reliability, and maintenance efficiency.
The selection of valve design also depends on the specific requirements of industries such as mining, chemical processing, power generation, and water treatment.
Based on material, knife gate valves can be manufactured using stainless steel, carbon steel, cast iron, ductile iron, and other materials.
Material selection is important because valves may be exposed to corrosive chemicals, abrasive slurries, high temperatures, or other demanding conditions. Stainless steel is preferred in applications requiring strong corrosion resistance, while cast iron and ductile iron are widely used in applications where durability and cost considerations are important.
Advances in material engineering are also supporting the development of valves with longer service lives and improved resistance to challenging operating environments.
Knife gate valves are used across several industries, including mining, pulp and paper, chemicals, power generation, oil and gas, water and wastewater treatment, and other industrial applications.
The mining industry represents an important application area because mining operations frequently handle abrasive slurries and solid-containing fluids. Similarly, pulp and paper facilities require specialized flow-control equipment for managing fiber-rich materials and processing fluids.
