FAQs

What is a Knife Gate Valve?

A Knife Gate Valve is basically a shut-off valve, meaning it is used to start and stop the flow through a pipeline. Knife Gate Valves are widely used in fluid-based applications and settings, especially those that involve dense materials.

How does a Knife Gate Valve work?

The ‘knife’ blade that is built into the valve uses the sharp edges to cut through tough or sticky materials. The Knife Gate Valve uses a pressure drop function to achieve this function and stop the flow when required. This ensures that the Knife Gate Valve sealing is not compromised due to the material being stuck between its components. It also ensures that any excess material is not creating any cleanliness issues for your product. If you require training on any valve and process equipment, check out our training options.

What is a Knife Gate Valve made from?

Knife Gate Valves are manufactured from a variety of materials, including stainless steel and carbon steel. The blades themselves are made from metals that are resistant to corrosion, rust, and general wear and tear, such as duplex stainless steel.

What are the typical uses of a Knife Gate Valve?

Knife Gate Valves are typically used in applications where the product is viscous, such as pulp, or slurry due to the fact that the knife edged blade cuts through the medium going through the pipe allowing the valve to provide a tight seal.

How long does a Knife Gate Valve last?

Knife Gate Valves, like many other types of valves, require regular servicing and maintenance if you want to extend their service life. There are a few different types and sizes of Knife Gate Valves available so it’s best to get in touch with a valve specialist so you can ensure you are getting the right product for your application.
