1. Product Description
A butterfly valve is a quarter-turn rotational motion valve used to regulate or isolate fluid flow. It consists of a circular disc (the “butterfly”) mounted on a rotating shaft, which controls flow by pivoting 90° from fully open to closed. Widely used in water treatment, HVAC, chemical, and oil/gas industries due to its compact design, quick operation, and cost-effectiveness.
