Butterfly Valves

(27 products)

Butterfly valves are quarter-turn valves used to regulate or isolate the flow of liquids, gases, or slurries. They consist of a rotating disc, known as the "butterfly," mounted on a shaft in the center of the pipe. When the valve is fully open, the disc is parallel to the flow, allowing fluid to pass through, and when it is turned 90 degrees, the disc blocks the flow entirely.

Butterfly valves are versatile and lightweight flow control devices used to regulate or isolate fluid flow in a wide variety of applications. These valves operate using a rotating disk as the closure mechanism, which pivots around a central axis to open, partially close, or fully block the flow path. Known for their compact design and ease of operation, butterfly valves are widely used in industries such as water treatment, HVAC, food and beverage, chemical processing, and power generation. Their ability to handle large flow rates while maintaining precise control makes them an essential component in fluid handling systems.

The key advantage of butterfly valves lies in their simple and efficient design, which minimizes weight and material usage compared to other types of valves. The disk, typically made from durable materials such as stainless steel, ductile iron, or plastic, is positioned in the center of the pipe and connected to an actuator on the outside of the valve body. Actuators may be manual (using a lever or gear) or automated (powered by pneumatic, electric, or hydraulic systems). This design allows for quick operation, making butterfly valves ideal for applications requiring frequent adjustments or fast shut-off.

Butterfly valves are available in various configurations, including wafer, lug, and double-flanged designs, to suit different installation and operational requirements. They are also offered in a range of materials and sizes, ensuring compatibility with diverse fluids, pressures, and temperatures. Easy to install and maintain, butterfly valves are a cost-effective solution for fluid management systems. Whether used for throttling or on/off flow control, their durability, versatility, and compact design make butterfly valves a popular choice across numerous industries, ensuring efficient and reliable system performance.

Advantages of Using Butterfly Valves

Compact Design

Butterfly valves have a slim and lightweight design compared to other valve types, such as gate or ball valves. This compact structure makes them ideal for applications with space constraints, reducing the overall footprint of the system.
Quick Operation

Like ball valves, butterfly valves operate with a quarter-turn (90 degrees), allowing for fast opening and closing of the valve. This rapid actuation is beneficial in processes that require quick shutoff or flow control.
Energy Efficiency

Butterfly valves create minimal pressure drop when fully open, allowing fluids to flow smoothly with minimal resistance. This contributes to energy savings by maintaining system efficiency, especially in high-flow applications.
Versatility

Butterfly valves can handle a wide range of fluids, including liquids, gases, and slurries. They are used in a variety of industries such as water treatment, chemical processing, HVAC systems, and food and beverage production.
Low Maintenance

Due to their simple design and fewer components, butterfly valves require less maintenance than more complex valve types. This results in reduced downtime and lower maintenance costs over time.
Tight Sealing

Modern butterfly valves are designed to provide a tight and reliable seal, even in high-pressure systems. This tight sealing capability ensures efficient flow control and prevents leakage in both open and closed positions.
