Types of valves used in
pneumatic conveying systems

Valves play a crucial role across various industries, serving to control the flow of gas and fluid through specific connection lines. With diverse types and functions, valves aid in redirecting or restricting the flow of substances within a system.

Industrial valves are designed to regulate, start, change, separate, or stop the flow of fluid or gas in a set direction. Besides that, they can also help ease excessive pressure from different vessels or systems.

There’s a whole variety of valve types for all wide range of applications. If you’re dealing with industrial setups that use valves for different reasons, understanding the various types is key. Let’s check out the different kinds of industrial valves!

Type of valves used in Pneumatic Conveying System

1. Butterfly Valve:

A butterfly valve is a quarter-turn valve used to control fluid flow in a pipeline. It’s called “butterfly” because the disc inside looks like a butterfly’s wings when it rotates. This disc sits in the middle of the pipe and when turned 90 degrees, it either allows or blocks the fluid flow. These valves are great for isolating vessels or in pneumatic conveying pipelines for handling bulk solids.

Butterfly valves are differentiated in terms of type of construction in the following ways:

Butterfly valves are widely used in various industries due to their simplicity, lightweight design, and relatively low cost. They are suitable for applications where tight shut-off is not critical, and a quick quarter-turn operation is desirable.

2. Knife Gate Valve:

A knife gate valve is a special type designed to cut through thick fluids using an edge blade. These valves are commonly used when you need straight-line fluid flow with minimal restrictions. They’re also used for isolating vessels or feeders handling bulk solids. They are typically designed for heavy loads.

The main types of knife gate valves used are:

3. Ball Valve:

Ball valves have a design with a big sphere and central hole for smooth fluid flow. They’re great at controlling high-pressure liquids and gases while reducing pressure drop. Their quick response time makes them efficient for fast opening and closing actions. Ball valves are versatile and perfect for different pneumatic conveying system applications. Here are some common types of ball valves used in pneumatic conveying:
