A butterfly valve is a type of quarter-turn valve used to regulate the flow of a fluid. It is widely used in various industrial applications due to its simple design, lightweight, and cost-effectiveness. Butterfly valves are essential components in many fluid control systems, offering a balance of performance, cost, and ease of use.

Whether it’s controlling the flow of water, gas, steam, or any other fluid, the pneumatic butterfly valve is one of the most common and reliable valves available. It comes in several different styles, configurations and options that can be tailored to suit a variety of applications and systems

Types of Butterfly Valves

• Concentric (Rubber-Lined) Butterfly Valve: The disc is centered in the pipe and the seat is made of an elastomer material.
• Double-Eccentric (High-Performance) Butterfly Valve: The disc is offset from the centerline, reducing wear and tear and allowing for higher pressure applications.
• Triple-Eccentric (Triple-Offset) Butterfly Valve: Features three offsets that provide a bubble-tight seal and are suitable for high-pressure and high-temperature applications.

Applications

1. Water Supply and Waste Treatment: Used for regulating and isolating flow in water treatment plants and distribution systems.


2. Chemical and Petrochemical Industries: Suitable for handling various chemicals, including corrosive substances.


3. HVAC Systems: Used in heating, ventilation, and air conditioning systems for flow control.


4. Food and Beverage Industry: Used for hygienic processing where stainless steel valves are preferred.
