Lugged Butterfly Valves

Lugged butterfly valves are a type of quarter-turn valve that is widely used in various industrial applications to control the flow of fluids, gases, or slurries. These valves feature a simple yet effective design, with a circular disc that is connected to a shaft positioned within the Valve body. The term Fully Lugged or Lug Butterfly Valves refers to the lugs or holes present on the valve's outer casing which are used to secure the valve in place between two flanges using bolts. This design feature makes installation and maintenance relatively simple when required. The valve can be easily isolated within the pipeline without disturbing the surrounding infrastructure.

Lugged Butterfly Valves FAQ

A lugged butterfly valve is equipped with threaded, lugged inserts on both sides of its body. This design allows for easy installation and disconnection from the process pipelines without having to completely remove the valve, making it suitable for dead-end service and frequent maintenance applications.
Key features of the TTV Lugged Butterfly Valves include threaded inserts on both sides of the Valve to allow for precise self-centering capabilities during installation, corrosion resistant materials, multi position lockable hand lever and worldwide recognised approvals and certifications.
One of the benefits of using a Lugged Butterfly Valves is easy, efficient and fast maintenance without disrupting the entire pipe system. Low pressure drops in the TTV range through the streamlined disc design allow for greater CV values and thus reduced energy costs. Typical applications include HVAC, Power Generation, Water & Marine.
Of course, they certainly can be. Lugged butterfly valves can be made from materials including CF8M Stainless Steel, Bronze and offer wetted parts including PTFE. Providing excellent resistance to corrosion and chemical solvents. These valves are ideal for use in highly corrosive environments such as marine, chemical, and petrochemical industries.
Yes, lugged butterfly valves excel as a solution for dead-end service applications.
The PTFE lined lugged butterfly valve offers an added layer of protection with a complete PTFE lining, making it extremely resistant to chemicals and solvents. It provides higher temperature ratings (up to 300°C) and with frequent maintenance and cleaning schedules can prevent cross-contamination.
Lugged butterfly valves allow for easy disconnection on either side of the pipeline without having to completely remove the valve, making maintenance faster and more straightforward compared to wafer pattern butterfly valves that require complete valve removal for maintenance. Lugged Valves offer self centering capabilities and point of installation whereas a wafer butterfly valve offers only guide lugs.
Yes, lugged butterfly valves, particularly those made from materials like aluminium bronze and stainless steel, are commonly used in the marine industry for applications such as fire protection, desalination, and ballast systems due to their resistance to extreme corrosive environments. These high quality exotic materials offer longer life expectancy when compared to materials such as ductile or cast iron.

Operations, Maintenance & Storage

TTV butterfly valves offer reliable and efficient flow control solutions for a wide range of applications, from fluid to gas services. To ensure optimal performance and longevity, proper operations, maintenance, installation, and storage practices are essential.

Operating TTV butterfly valves within the specified limits is crucial. Exceeding temperature and pressure ratings can lead to damage of internal and external sealings or castings. Always verify the open and closed direction when mounting pneumatic or electric actuators, ensuring proper valve positioning. TTV lugged butterfly valves require minimal maintenance, however periodic cleaning is recommended. Dismantling any part of the valve while it is installed or operational in the pipeline, especially when fluid is present, is strictly prohibited and may void warranty or cause harm to the operator.

Prioritise careful installation to prevent damage during this process. Ensure adequate space is available for valve placement and follow a cross triangular tightening method for nuts. This will allow uniform tightening without deformation of the valve liners. Flanged type valves should use complete passing bolts and nuts, not screws with nuts. During extended storage periods, maintain a controlled environment with temperatures not exceeding 25°C and low humidity to avoid condensation. Protect the valves from direct sunlight and contact with corrosive substances. Avoid deformation and store away from materials such as copper or manganese, solvents, grease, oil, and dusty materials. Correct operations, maintenance, installation, and storage are paramount to ensuring the longevity and efficiency of the performance of TTV lugged butterfly valves.
