What Is a Gate Valve?

A gate valve is a shut-off valve designed to fully open or completely close the flow of a medium in a pipeline. Unlike control valves, gate valves are not intended for throttling flow – their design allows for a fully open flow passage, minimizing pressure loss within the system.

The operating mechanism is based on the vertical movement of a wedge, plate, or knife, which rises during opening and lowers to tightly shut off the flow when closing the valve.
Thanks to their simple, robust design and ability to operate under a wide range of pressure and temperature conditions, industrial gate valves are among the most commonly used shut-off valves.

Applications of Industrial Gate Valves

Our industrial gate valves are widely used in many industries, including:

chemical and petrochemical industry,

Knife Gate Valves – Distribution and Applications

Flow-Valves is a distributor of specialized industrial valves, including high-quality knife gate valves. We deliver solutions that combine reliability, durability, and precise operation in the most demanding industrial environments. Our knife gate valves are widely used in the chemical, food processing, pulp and paper, as well as water and wastewater industries.

What Is a Knife Gate Valve?

A knife gate valve, also known as a wafer knife gate valve, is a valve that controls the flow of a medium by raising or lowering a blade. The blade movement is perpendicular to the direction of flow, allowing effective shut-off of liquids, slurries, and bulk solids.

This type of valve is characterized by a simple design, compact dimensions, low weight, and excellent tightness. As a result, it is widely used across many industrial sectors, especially in applications requiring efficient flow isolation under harsh operating conditions.

Design and Operating Principle

The design of a knife gate valve is based on a full-bore body and a movable knife. The knife moves up and down to open or close the flow of the medium.
Thanks to the full-bore design, the valve offers low flow resistance and allows the free passage of media with high density.

Unlike traditional wedge gate valves, knife gate valves can effectively cut through and remove solid particles, fibers, or contaminants present in the medium. Their ultra-short face-to-face length, lightweight construction, and ease of installation and maintenance make them a highly practical solution for industrial applications.

Additionally, the valve sealing can be replaced without dismantling the entire valve, significantly reducing installation downtime and maintenance costs.
