Worm Wheel Operated Wafer Butterfly Valve

  The clamp Butterfly Valve is simple in structure, small in size and light in weight, It consists of only a few components. And it can be opened and closed quickly only by rotating 90 degrees. The operation is simple, and the valve has good fluid control characteristics. When the butterfly valve is in full opening position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop produced through the valve is very small, so it has a better flow control characteristic. Butterfly valve has two kinds of seal: elastic soft seal and metal seal. The elastic soft sealing valve can be set on the valve body or attached to the butterfly plate.
