Product Description
Operating Principle: A butterfly valve belongs to the elite family of quarter-turn valves, renowned for their efficiency and simplicity. In operation, this valve is ingeniously designed to be fully open or closed when the disc is rotated a mere quarter turn. The 'butterfly' component is a precision-engineered metal disc mounted expertly on a sturdy rod. When closed, the disc turns to form a perfect seal, completely obstructing the passageway. Conversely, when the valve is in the open position, the disc rotates a quarter turn, offering an almost unimpeded path for fluid flow. Moreover, the valve's design allows for it to be opened incrementally, providing the flexibility to regulate flow with precision. Product Application: This versatile valve is ideal for managing the flow of water, oil, air, and even certain corrosive liquids, showcasing its adaptability across various applications.
