Industrial valves play a crucial role in regulating the flow of liquids, gases and slurries across a wide range of systems. Among the many types available, butterfly valves are frequently chosen for their compact design and efficient operation. However, selecting the right valve type depends on various technical factors, including application, media, space, and pressure requirements.
In this guide, we’ll explore how butterfly valves compare to other commonly used valve types and help you determine which is best suited for your specific needs.
Understanding the Function of Industrial Valves
Industrial valves are mechanical devices used to start, stop, and regulate the flow of fluids within a system. They are essential in maintaining process control, protecting equipment, and ensuring safe operation across a variety of installations. Whether managing water, oil, gas or other media, valves allow operators to fine-tune system performance with precision and reliability.
Different valve types offer different operational benefits, making the correct selection vital. Factors such as flow rate, pressure, temperature, and compatibility with the media must all be considered during specification. Choosing the wrong valve can result in inefficiency, equipment damage, or process failure.
Common Applications Across UK Industries
Across the UK, industrial valves are found in sectors where flow control is integral to daily operations. In agriculture, they manage irrigation and fertiliser distribution systems. In construction, they are used within water supply lines, heating systems and fuel handling equipment. Transport and logistics often rely on valves in hydraulic and pneumatic systems, particularly in commercial vehicles and plant machinery.
In utilities and waste management, valves help control the flow of water, steam, and chemicals, ensuring safety and regulatory compliance. Manufacturing and process industries depend on reliable valve performance to maintain product consistency, especially in sectors like food production, pharmaceuticals, and chemicals.
What Is a Butterfly Valve and How Does It Work?
Butterfly valves are quarter-turn valves designed for fast and efficient flow control. They consist of a rotating disc mounted on a central shaft. When the handle or actuator turns the shaft, the disc pivots to either allow or restrict the passage of fluid. Their streamlined mechanism and minimal moving parts make them a popular choice in systems where space, speed, and cost are critical factors.
The compact design of butterfly valves allows them to be installed in tight locations, and they can operate at a wide range of pressures and temperatures, depending on material specification. While they are not suitable for every application, they offer specific benefits that make them a strong option in many industrial systems.
Key Advantages of Butterfly Valves
Butterfly valves are valued for their compact footprint and cost-effective performance. Compared to many other valve types, they are lighter in weight and require less support, which simplifies installation and reduces pipework strain. Their quarter-turn operation enables fast actuation, making them ideal for systems that require quick shut-off or changeover.
Their design also supports good flow characteristics with relatively low pressure drop when fully open. Maintenance is minimal due to fewer moving components, and the valves are generally easy to operate, whether manually or with automated actuators.
Typical Use Cases for Butterfly Valves in the UK Market
In the UK, butterfly valves are widely used in applications where space and weight savings are important, or where large diameter pipework requires reliable shut-off. Water treatment facilities use them to control flow through filtration and chemical dosing systems. In HVAC and building services, they regulate chilled and heated water circuits.
They are also common in food processing and pharmaceutical plants, where hygienic designs are available. In agricultural settings, butterfly valves help manage irrigation systems and slurry handling. Their quick actuation makes them a good fit for fire protection systems and emergency isolation lines as well.
Comparing Butterfly Valves to Other Common Valve Types
Selecting the right valve involves understanding how each type performs in relation to the application’s specific demands. Butterfly valves are not the only option available for flow control, and alternatives like gate, ball, globe, and check valves each offer unique characteristics. These differences can influence factors such as sealing ability, throttling precision, and suitability for high-pressure systems.
In the sections that follow, we’ll compare butterfly valves directly to each of these common valve types. This will help clarify when a butterfly valve is the best fit and when an alternative may be more appropriate. We’ll start with how butterfly valves compare to gate valves.
Butterfly Valve vs Gate Valve
Gate valves operate by lifting a gate or wedge out of the flow path, providing a straight-through, unobstructed passage when fully open. They are typically used in systems where minimal pressure drop is essential and infrequent operation is expected. However, gate valves are slower to actuate and require more space due to their multi-turn mechanism.
In contrast, butterfly valves provide quicker operation with a compact, quarter-turn design. While they may introduce slightly more flow restriction when open, they are generally easier to install and maintain. For applications where rapid shut-off or space-saving is a priority, butterfly valves often provide a more practical solution.
Butterfly Valve vs Ball Valve
Ball valves use a rotating ball with a bore to control flow and are known for providing tight shut-off with minimal leakage. They perform well in high-pressure systems and are ideal for applications requiring frequent on/off operation. However, they can be bulkier and heavier than butterfly valves, particularly in larger sizes.
Butterfly valves offer a more space-efficient alternative and are typically more cost-effective for larger diameter pipelines. While ball valves may provide superior sealing in some systems, butterfly valves are often preferred where compact installation, reduced weight, and lower cost are key considerations.
Butterfly Valve vs Globe Valve
Globe valves are designed for precise flow regulation and throttling. Their internal structure forces fluid to change direction, which allows for better control but results in a higher pressure drop. They are commonly used in applications where accurate flow adjustment is required, such as in steam systems or chemical processing lines.
Butterfly valves, while capable of limited throttling, are better suited to on/off control or systems where moderate flow regulation is sufficient.
Butterfly Valve vs Check Valve
Check valves are designed to allow flow in one direction only, automatically preventing backflow without manual intervention. They rely on differential pressure to operate and are often used in pump discharge lines, water systems, and process circuits where reverse flow could damage equipment or disrupt operations.
Butterfly valves, by contrast, are manually or automatically controlled and are not intended to function as non-return devices. While both may appear in similar systems, they serve entirely different purposes. In many setups, butterfly valves work alongside check valves to provide both flow control and backflow prevention.
Pressure and Flow Control Considerations
When specifying a valve, pressure rating and flow control capabilities are key factors. Butterfly valves generally perform well in medium-pressure systems and offer good flow characteristics with minimal obstruction when fully open. However, they may not be ideal for high-pressure or vacuum applications without proper material selection and sealing design.
Compared to globe or ball valves, butterfly valves are less suited for precision throttling but provide a practical balance between control, installation ease, and cost. They are especially efficient in large-bore applications where maintaining a steady flow is more important than ultra-fine regulation.
