Industrial Knife Gate Valve
Industrial Knife Gate Valves for Process Isolation
A knife gate valve uses a sliding gate to open or close the flow passage. When the gate moves into its closed position, it provides isolation according to the valve's seat construction and leakage performance.
The knife-style gate makes this construction worth considering for selected applications involving suspended solids, slurry-like fluids and industrial process media.
Buyers researching knife gate valves manufacturer options should compare technical specifications rather than relying on nominal size alone. Pressure rating, seat selection, body material and installation conditions all matter.
Ultra Valves Automation Pvt. Ltd. is a point of contact for industrial knife gate valve enquiries in Mumbai and throughout India.

How Does a Knife Gate Valve Work?
A knife gate valve operates by moving a gate into or out of the pipeline's flow passage.
Open Position
The gate is raised away from the flow passage, allowing the process medium to pass through.
Closing Movement
The gate moves downward and progressively reduces the available flow area.
Closed Position
The gate reaches its closed position to provide isolation according to the valve's seating and leakage performance.
Knife Gate Valve Size Guide
Knife gate valves are often requested by nominal inch size. Confirm the exact DN size and configuration before ordering.
A 150mm knife gate valve generally corresponds to nominal DN150 (approximately 6 inches). A 36 knife gate valve falls outside the supplied 2″–34″ range and requires separate confirmation.
Types of Knife Gate Valves
Knife gate valves may use different body connections, materials and seating arrangements.
Wafer Knife Gate Valve
A wafer design is installed between pipeline flanges. Lugged and semi-lugged configurations are listed.
Flanged Knife Gate Valve
A flanged design is considered where the piping arrangement requires a suitable bolted flange connection.
Stainless Steel Knife Gate Valve
A stainless steel knife gate valve may suit selected applications requiring compatible stainless materials such as CF8 or CF8M.
Metal-Seated Knife Gate Valve
Metal seating may be considered for suitable higher-temperature duties, subject to complete design verification.
Soft-Seated Knife Gate Valve
O-ring and PTFE/RPTFE seating options have different operating temperature limitations.
Industrial Knife Gate Valves
Industrial knife gate valves may be considered for suitable slurry and solids-bearing fluid isolation.
Where Knife Gate Valves Are Used
The correct application depends on the process medium, seat design and operating conditions.
Pulp & Paper
Suitable stock handling and process isolation duties.
Wastewater Treatment
Selected wastewater and sludge handling systems.
Mining & Minerals
Suitable slurry handling and industrial isolation.
Chemical Processing
Compatible fluid isolation applications.
Power Plants
Selected utility and process isolation duties.
Manufacturing Plants

Understanding Knife Gate Valve Search Terms
Industrial buyers may use short descriptions such as knife gate, knife valve, gate valve knife type or 3 knife valve when searching for a particular valve design or nominal size.
Size-related searches also include 10 knife gate valve, 3 inch knife valve, 8 knife gate valve, 16 knife gate valve and 18 knife gate valve. Always confirm the exact nominal size and connection dimensions.
Some projects specify a trueline knife gate valve or another branded design. If an alternative valve is being considered, compare the approved technical drawings, dimensions and performance requirements rather than assuming interchangeability.
When comparing knife valve manufacturers, focus on technical suitability, material compatibility and verified documentation. The right valve should match the actual process requirements.
