Knife valves are primarily used for on-off and separation functions in systems with a high suspended solids concentration. They’re particularly useful for working with slurry, fluid, corrosive, and gritty media.
The gates have a modest pressure drop in the free field, are simple to operate, have a low density, and are cost efficient.
The knife gate valve’s horizontal design features are ideal for a pneumatic system, and the arising air powered knife gate valve is portable in a face to face aspect, lightweight than a traditional wedge gate valve, and provides an economical solution for fully automated isolation implementations.

Uses of A Pneumatic
Knife Gate Valve
Source: Pinterest
Knife gate valves, which often have a sharpened edge to cut past heavy liquids, are developed to function in some of the hardest settings.
- When it comes to water and wastewater treatment, corrosion is a big deal.
- Flow regulation should not be employed in industrial valve applications that require a totally open or closed state unless they are specifically built for it. There will be a tremor whenever fluid is pressed against a partly closed gate, progressively degrading the gate.
- A vibration occurs whenever fluid is pressed against a partially locked gate, progressively eroding the disc and seat.
- Slurries
- heaviest oils
- Viscose fluids that aren't flammable
- Wastewater
- Water that is free of contaminants
Stainless steel gate valves are often found in potable water mains, distribution channels, and potable water pump stations, whereas knife gate valves are typically found in sewage treatment plants, chemical industries, mining, cement factories, and a variety of other industrial applications.
