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:

Concentric Butterfly Valve

It is the most common type of butterfly valve the where, the shaft which connects the actuator to the disc of butterfly valve known as ‘stem’ is positioned at the center of the disc.

Lug-style Butterfly Valve

This valve has threaded inserts at both sides of the valve body. The valve is mounted between two flanges.

Eccentric Butterfly Valve

The stem of this valve is located off-center, which allows for a more resilient seating arrangement. There are two types: high-performance valves and triple offset valves. High-performance eccentric valves have a slightly offset stem, while triple offset valves have a more pronounced offset.

Wafer-style Butterfly Valve

This valve is designed to fit between two flanges without the need for bolts and nuts through the flange holes, typically 4 in number. It is held in place by the flanges.

Flanged Butterfly Valve

This valve is installed between two flanges using bolts and nuts to secure it in place. It is suitable for applications where the pipeline has flanges at both ends.

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.

Three-Way (Diverter) Ball Valve

These valves have three ports and can redirect the flow of air or material between two different paths. Used for diverting air flow to different destinations within the pneumatic conveying system.

V-Port Ball Valve

These valves have a V-shaped port in the ball, allowing for more precise control of flow by partially opening or closing the valve. Used in applications where throttling or modulating the flow is required.

Full-Port Ball Valve

These valves have a larger port size, providing minimal restriction to flow and reducing pressure drop. Suitable for applications where maximizing flow capacity is important.

Trunnion-Mounted Ball Valve

provides additional support for the ball , ensuring stability and reducing pressure on it . Used in high-pressure pneumatic conveying systems.

Metal-Seated Ball Valve

These valves have metal seats, providing better wear resistance and durability, especially in applications with abrasive materials. Suitable for handling abrasive materials in pneumatic conveying systems.

Floating Ball Valve

The ball in these valves is not fixed and can move slightly to ensure a tight seal against the seats. Used in applications where a tight seal is crucial to prevent leakage.

Cavity Filled Ball Valve

These valves have a cavity filled with a sealing material to enhance sealing performance. Suitable for applications requiring enhanced sealing in pneumatic conveying.

Butterfly, ball and knife gate valves can be operated using various methods, including manually, electrically, pneumatically, or hydraulically. The choice of actuation method depends on the specific application requirements and the preferences of the system designer. These valves are commonly actuated by the following methods:

1. Manual Operation:

Handwheels or levers are used to manually turn the stem and control the position of the disc or gate.

2. Pneumatic Operation:

Compressed air is used to actuate the valve. Pneumatic actuators are common for these valves, especially in applications where quick and efficient operation is needed.

6. Indoor dust collector or outdoor dust collector

The decision to opt for an indoor or outdoor dust collector depends on various factors, such as available space, environmental conditions, and specific industry requirements. Indoor dust collectors are typically used when product recovery is important to the process and space is not a constraint. On the other hand, outdoor dust collectors are suitable for applications where large volumes of dust are generated or where space is a constraint. By evaluating the specific needs of your facility, you can determine whether an indoor or outdoor dust collector is the right choice for your dust control needs.


7. Installation requirements

To ensure the proper functioning of the dust control system, it is essential to consider the installation requirements. This includes evaluating the available utilities, such as electricity and compressed air, which are necessary for the operation of the system. Additionally, understanding the space requirements, such as the height, width, and clearance, will assist in selecting a dust collector that can be easily accommodated in your facility. Evaluating the installation requirements will help you avoid any potential challenges or delays during the setup process.


8. Understand the working principles of dust collectors based on their types

Different types of dust collectors utilize varying mechanisms to capture and separate dust particles from the air. It is important to understand the working principles of dust collectors to select a system that aligns with your needs. Baghouses filter, cartridge filter, cyclone separators, Pulse jet filter, electrostatic precipitators and wet scrubbers are some of the common types of dust collectors. Every category comes with its unique set of advantages and limitations. By gaining a comprehensive understanding of these mechanisms, you can choose a dust collector that best suits your application and maximizes dust control efficiency.


9. Value for money

While cost is an important consideration, it should not be the sole deciding factor when selecting a dust control system. Evaluating the value for money involves considering factors such as initial cost, maintenance requirements, energy efficiency, and lifespan of the equipment. A dust control system that may have a higher upfront cost but offers better filtration efficiency and longer lifespan can result in cost savings in the long run. Balancing the initial investment with long-term benefits will help you make a financially sound decision.


10. What kinds of support do you expect from your dust collector after\-sales service?

The after-sales service and support provided by the dust collector manufacturer should not be overlooked. When selecting a dust control system, consider the level of technical support, availability of replacement parts, and warranty offered by the manufacturer. A reliable after-sales service ensures that any issues or concerns with the dust control system can be promptly addressed, minimizing downtime, and maximizing the performance of your dust control solution.

Choosing the right dust control system for your industrial application is crucial for maintaining a safe and healthy work environment. By considering factors such as your specific application, dust characteristics, sizing requirements, setup location, type of dust collector, installation requirements, working principles, value for money, and after-sales support, you can make a well-informed choice that aligns with your specific requirements. Remember, investing in an effective dust control system not only protects the well-being of your workforce but also ensures the longevity and productivity of your equipment. So, take the time to evaluate these factors and choose a dust control system that will safeguard both your employees and your business.
