Round Port Knife Gate Valve
The Round Port Knife Gate Valve is engineered for applications requiring efficient flow control in slurry, viscous, or abrasive media. Unlike standard knife gate valves, its round port design minimizes turbulence and pressure drop, ensuring smooth flow through the valve. Ideal for industries such as mining, pulp & paper, wastewater treatment, and chemical processing, this valve combines durability with reliable sealing performance.

Round Port Knife Gate Valve – FAQ
A round port knife gate valve is designed with a circular flow port that allows slurry, viscous, or abrasive media to pass through with minimal turbulence and pressure drop. Its gate cuts through solids, ensuring reliable flow control in demanding applications.
Unlike standard rectangular or full-bore designs, the round port valve features a circular opening that reduces turbulence and energy loss, improving flow efficiency while maintaining tight shutoff.
Sizes typically range from 2" to 48", with pressure classes from PN10, PN16 up to ANSI 150–300. Custom sizes and pressure ratings are available on request.
Common body materials include cast iron, carbon steel, stainless steel, and duplex steel. Seat options include resilient rubber, PTFE, or metal, depending on the application requirements.
Round port knife gate valves can be operated manually, via gear, pneumatic, hydraulic, or electric actuators, allowing flexible integration into any system.
Yes. The reinforced gate and body, along with the round port design, make these valves ideal for abrasive media, slurries, and viscous fluids in industries like mining, wastewater, and pulp & paper.
