Cast Steel EPDM Lined Lug Type Concentric Butterfly Valve with Worm Gear Operated
Lug Type Butterfly Valves operate in a similar way to ball valves. However, instead of a ball being positioned in the valve body, there is a circular disc (referred to as a butterfly due to its resemblance to wings) surrounding a vertical shaft.
The flowrate is determined by the orientation of the butterfly. When the butterfly is aligned with the pipe, allowing the least amount of space for the fluid to pass through, there will be unrestricted flow.
As the butterfly moves away from the pipe's direction, the flowrate will be limited due to the increased obstruction caused by the larger surface area. Eventually, when the butterfly is perpendicular to the pipe, the flow will be completely shut off.

Stainless steel butterfly valves have a wide range of applications in various industries and settings. Some common applications of stainless steel butterfly valves include:
1. Water and Wastewater Treatment: Stainless steel butterfly valves are commonly used in water and wastewater treatment plants. They are used to control the flow of water, chemicals, and other fluids in processes such as filtration, disinfection, and sludge handling.
2. Food and Beverage Industry: Stainless steel butterfly valves are widely used in the food and beverage industry due to their sanitary properties and resistance to corrosion. They are used to control the flow of ingredients, beverages, and cleaning solutions in production processes and distribution systems.
3. HVAC Systems: Stainless steel butterfly valves are used in heating, ventilation, and air conditioning (HVAC) systems to control the flow of air and water. They help regulate temperature, pressure, and flow rates in commercial and residential buildings.
4. Chemical and Petrochemical Industry: Stainless steel butterfly valves are suitable for handling various chemicals and corrosive fluids. They are used in chemical processing plants, refineries, and petrochemical facilities to control the flow of acids, solvents, and other aggressive substances.
5. Power Generation: Stainless steel butterfly valves are utilized in power plants to control the flow of steam, water, and other fluids in boiler systems, cooling towers, and other power generation processes.
6. Pharmaceutical Industry: Stainless steel butterfly valves are employed in pharmaceutical manufacturing facilities to control the flow of fluids during the production of medications and other pharmaceutical products. They meet the stringent sanitary standards required in the industry.
7. Oil and Gas Industry: Stainless steel butterfly valves are used in oil and gas pipelines, refineries, and offshore platforms to control the flow of crude oil, natural gas, and other hydrocarbons.
8. Marine and Shipbuilding: Stainless steel butterfly valves are commonly used in marine and shipbuilding applications. They help control the flow of water, fuel, and other fluids on ships, offshore rigs, and other marine vessels.
9. Fire Protection Systems: Stainless steel butterfly valves are utilized in fire protection systems to control the flow of water or fire-suppressing agents in sprinkler systems and fire hydrants.
These are just a few examples of the applications of stainless steel butterfly valves. Their versatility, durability, and resistance to corrosion make them suitable for a wide range of industries and fluid control systems.
