V-Port Knife Gate Valve

Your All-in-One Flow Control Solution for Slurries, Fibers, and Tough Process Fluids

If you’re dealing with flow systems that involve thick slurry, pulp, or semi-solid fluids, you know that standard isolation valves just don’t cut it—literally. That’s where the V-port knife gate valve, also known as a V-notch knife gate valve, makes all the difference.

And if your system deals with variable flow, solids build-up, or harsh chemicals, you can count on this flow control knife gate valve to perform reliably with minimal maintenance.

Whether you need 1 piece or more, we can deliver tested, performance-qualified products on time.

Description

The V Port Knife Gate Valve is a type of modulating knife gate valve designed with a V-cut in the gate. This allows you to regulate flow with far greater precision than conventional on/off knife gates. Unlike a simple shut-off valve, this one handles partial open conditions with stability, repeatability, and control.

You’ll benefit from a valve that not only cuts through solids, but also enables linear or equal-percentage flow profiles, turning your isolation valve into a throttling knife gate valve that delivers true process control.

TOT Valve By integrating precise throttling capabilities into a rugged knife gate design, this valve gives you both accurate flow modulation and tight shut-off in one compact body. Whether you’re in pulp & paper, wastewater, mining, or chemical processing, this is the control knife gate valve you’ve been looking for.

Applications That Require High Reliability

You need a valve you can trust—especially in demanding environments. Here’s where the V Port Knife Gate Valve truly shines:

Pulp & Paper Industry: Control the flow of pulp slurry, recycled fibers, and white water with precision
Mining and Mineral Processing: Throttle abrasive tailings, ore slurry, and thickened waste with minimal wear
Wastewater Treatment Plants: Handle sludge and digestate with reliable shut-off and smooth modulation
Chemical and Petrochemical Plants: Tolerate corrosive and viscous media in tight, automated process lines
Power Generation: Regulate cooling water, fly ash slurry, and blowdown flows under tough conditions
Bulk Material Handling: Control dry solids, powders, or granules in gravity or pneumatic conveyors

Need a knife gate valve that works on your terms? You shouldn’t have to choose between isolation and control. TOT With a V-port knife gate valve, you get both—engineered for high performance and built to your specs. If you’re upgrading from a standard gate valve or searching for a more reliable modulating knife gate valve, our are ready to assist.
