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.
Lugged butterfly valves are available in a wide range of sizes to suit various industry standards. Common sizes include 2" to 12" with ANSI or DIN flanged connections. Manufacturing capabilities up to 128" from factory.
Yes, lugged butterfly valves, like those from our Spanish Manufacturing partner TTV, are designed for easy installation in various environments, including marine, offshore, and harsh conditions. They are tested to meet multiple industry standards and have been independently verified from bodies such as DNV, Bureau Veritas & FDA (Model dependant).
