FAQ's

A lugged butterfly valve is a type of quarter-turn valve that controls the flow of fluids in a pipeline system.

It consists of a disc or plate that rotates inside the valve body to regulate the flow. The “lugged” aspect refers to lugs or holes on either side of the valve’s body, allowing it to be easily mounted between two flanges using bolts.

The operation of a lugged butterfly valve is relatively simple yet highly effective. When fully open, the disc aligns with the flow direction, minimizing any pressure drop across the valve. Conversely, when closed, the disc creates a tight seal against the seat, preventing leakage.

There are many types of butterfly valves. Lug butterfly valves are one of the most popular kinds.

In terms of applications, lugged butterfly valves find extensive use in industries such as water treatment plants, HVAC systems, chemical processing plants, and food processing facilities. Their versatility allows them to handle various fluids, including liquids and gases.

When controlling the flow of fluids, a lugged butterfly valve offers numerous advantages that make it a preferred choice in various industries. Lug-style butterfly valves are specially designed to provide efficient and reliable performance, ensuring smooth operation and optimal flow control.

  • Versatility: These valves can be easily installed in both low-pressure and high-pressure systems, making them suitable for a wide range of applications. The lugged butterfly valve can effectively regulate the flow of liquids, gases, or slurries, whether in water treatment plants, HVAC systems, or industrial processes.
  • Compact design and lightweight construction: The lugged butterfly valve takes up minimal space compared to other valves, making it ideal for installations where space is limited. Additionally, its lightweight nature reduces stress on piping systems and simplifies maintenance procedures.
  • Excellent sealing capabilities: Its unique design ensures a tight seal when closed, preventing any leakage or backflow that could compromise system efficiency or safety. This reliable sealing mechanism minimises energy loss and enhances overall system performance.
  • Cost-effective: Its simple construction requires fewer components than other valves, reducing manufacturing costs and installation expenses. Moreover, its low maintenance requirements contribute to long-term cost savings for businesses.
  • Easy to operate: With its simple lever or gear-operated mechanism, users can easily control the opening and closing actions without much effort. This simplicity improves operational efficiency and reduces training time for personnel responsible for valve operation.

There are two commonly used butterfly valves: lug type and wafer type.

Lug-type butterfly valves are designed with threaded inserts, or lugs, on both sides of the valve body.

These lugs allow easy installation and valve removal from a pipeline without disrupting the flow. The lugs also provide stability and prevent valve movement during operation, making lug-type butterfly valves ideal for applications requiring frequent maintenance or replacement.

On the other hand, wafer-type butterfly valves are designed with a slim profile and do not have lugs or flanges. Instead, they rely on being sandwiched between two flanges using bolts or studs.

The design of wafer butterfly valves allows for easy installation and removal but may require shutting down the pipeline to remove or replace the valve.

Choosing between lug-type and wafer-style butterfly valves depends on several factors, including system pressure, temperature, size requirements, and maintenance considerations. Lug-type butterfly valves are generally recommended for high-pressure applications where frequent maintenance is anticipated. In contrast, wafer-type butterfly valves are often used in low-pressure systems that require quick installation and removal.
