A butterfly valve is a quarter-turn rotary valve featuring a disc that pivots inside the valve body to control flow. They are known for their simple design, ease of operation, and relatively low cost.

Features:

• Simple and Compact Design: Butterfly valves have a straightforward design with a disc and a rotating shaft, making them relatively compact for their size.
• Easy Quarter-Turn Operation: The valve opens and closes with a simple 90-degree rotation, requiring less space than valves needing multiple turns.
• Good Flow Regulation: Butterfly valves offer good flow control when fully open, with minimal pressure drop across the valve.
• Limited Pressure Rating: Generally not rated for high-pressure applications compared to other valve types.
• Not Ideal for Throttling: Due to the disc design, butterfly valves are not ideal for precise flow control or throttling applications.
