Lug-Type Butterfly Valve
Lug type butterfly valves are used in industries for controlling as well as isolating the flow of fluids. These valves have lugs attached to the body of the valve which makes it possible to mount the valve between two pipes using individual bolts. These valves are designed such that sometimes they can even be used in end-of-line applications.
These valves work through the rotating disc which controls the flow of gases and liquids. Industrial businesses searching for a lug type butterfly valve manufacturer can use the following criteria to choose the right valve for them. Businesses that search for lug type butterfly valve manufacturer in Ahmedabad can use the following criteria to find the right choice.
Key Features of Lug-Type Butterfly Valves
Threaded Lug Design
Holes present in the valve body that are threaded enable bolted connections to matching flanges in the pipeline.
Convenient Maintenance
In some installations, it is possible to disconnect one side of the pipeline while leaving the valve fastened on the other side based on the design of the valve and its pressure capability.
Quarter-Turn Operation
It turns through an angle of about 90 degrees from full open to full close position.
Compact Construction
Butterfly valve construction saves on space of installation as compared to some valve types.
Flexible Operating Options
Based on the model, the valve can either be manually operated or with a gearbox, electric, and pneumatic actuators
Application-Specific Materials
Body, disc, and seat material selection is made based on the type of fluid, temperature, pressure, and sealing capabilities required. Applications
Applications
Water Treatment and Distribution
The lug-type butterfly valves are utilized in water treatment plants, distribution systems, and filtration systems where the regulation of flow and isolation for maintenance of certain portions of pipeline are required.
Wastewater Management
These valves may be utilized in appropriate wastewater handling systems where the isolation of pipes and maintenance are required.
HVAC Systems
They help to regulate the water flow in chilled-water lines and in heating circuits of the commercial and industrial facilities.
Chemical Processing
These valves may be employed in appropriate chemical process lines provided that the body, disc, and seat materials correspond to the demands of the flowing liquid.
Power and Utility Plants
These valves may be used in selected cooling-water and auxiliary pipelines of power plants where the pressure and temperature ratings correspond to the service conditions.
Industrial Manufacturing
The manufacturing industry employs the lug-type butterfly valves in process and utility pipelines.
Lug-Type Butterfly Valve Supplier in India
Selection of a suitable lug type butterfly valve depends on a number of factors including pipe diameter, flange code, pressure rating, temperature range, fluid characteristics, and the installation configuration. In case the valve is designed for end-of-line configuration, it needs to be checked whether the chosen configuration suits this purpose.

Frequently Asked Questions
What is a lug-type butterfly valve?
It is a butterfly valve whose body is provided with threaded lugs that enable the valve to be bolted to suitable pipeline flanges. Flow is controlled through the pipeline by means of a rotating disc
What is the difference between a lug-type and a wafer-type butterfly valve?
Lug-type valves have threaded lugs that bolt onto the pipeline flanges whereas wafer-type valves are usually retained between flanges using the desired bolting arrangement.
Can a lug-type butterfly valve be used for end-of-line service?
Yes, some lug-type valves can be used for end-of-line applications but this will depend on the construction of the valve as well as the pressure rating and instructions from the manufacturers.
Which industries use lug-type butterfly valves?
Water treatment, wastewater treatment, HVAC systems, chemical processing, power utilities and general industry pipelines.
What should I check before selecting a lug-type butterfly valve?
Valve size, flange rating, pressure and temperature ratings, fluid being handled, material of body and seats and method of operation.
