The double-plate check valve , two-lobed circular disc fixed on the valve body with a pin shaft. There are two torsion springs on the pin shaft. The disc is installed on the sealing surface of the valve body, and the spring is pressed by the medium pressure. The butterfly plate, when the flow is reversed, closes the valve by spring force and medium pressure. This kind of butterfly check valve is mostly of wafer structure, small in size, light in weight, reliable in sealing, and can be installed in horizontal pipelines and vertical pipelines.
