A Wafer Type Butterfly Valve is a compact valve designed to fit between two pipeline flanges without requiring additional bolts or a long face-to-face connection. It consists of a circular disc mounted on a rotating shaft, which turns 90° to control flow. When the disc is parallel to the flow, the valve is fully open, providing minimal resistance; when perpendicular, it completely shuts off the flow.

Wafer type butterfly valves are widely used in water supply, HVAC, chemical, and industrial pipelines where space is limited and a lightweight, cost-effective valve is required. Their simple design, quick quarter-turn operation, and reliable sealing make them ideal for large-diameter pipelines and systems requiring efficient flow control. They are available in various materials and sizes to suit different pressure and temperature requirements.
