Knife Gate Valve Manufacturers in USA
A knife gate valve is a critical isolation valve used in industrial piping systems handling slurry, viscous fluids, and solids-laden media. Designed with a sharp-edged gate, these valves provide reliable shut-off with minimal clogging, making them ideal for harsh and abrasive service conditions.
SVR Global is a leading Knife Gate Valve Manufacturers and Supplier in USA, delivering engineered knife gate valve solutions for mining, pulp & paper, wastewater treatment, power plants, and chemical processing facilities. Our knife gate valves are designed for dependable isolation, smooth operation, and long service life in both standard and severe-service applications.
With extensive experience supporting EPC contractors and plant operators, SVR Global supplies knife gate valves that meet stringent project specifications and international isolation valve standards.
What Is a Knife Gate Valve?
A knife gate valve is a linear motion isolation valve designed to cut through thick fluids, slurries, and solids. The sharpened gate moves vertically to open or close the flow path, allowing effective shut-off in applications where conventional gate valves may clog due to media buildup.
Knife Gate Valve Applications in Industrial Systems
SVR Global knife gate valves are widely used in demanding industrial applications, including:
- Slurry handling and mineral processing systems
- Wastewater and sewage treatment pipelines
- Pulp and paper stock and fiber processing lines
- Power plant ash handling systems
- Chemical and industrial process pipelines
These applications require valves capable of handling abrasive media, solids accumulation, and frequent operation with reliable sealing.
