Hard seal butterfly valve is a type of valve that uses a disc-shaped closure element, known as the butterfly disc, to regulate the flow of fluid. It is called "eccentric" because the centerline of the shaft or stem is located off-center from the centerline of the disc.

This type of butterfly valve is equipped with a metal-to-metal sealing mechanism, which provides a tight and durable seal against the flow of fluid. The sealing surfaces of the valve, such as the disc and the seat, are made of metal materials that can withstand high pressures and temperatures.
