Product Advantage

Check valve, also known as one-way valve, check valve, back pressure valve, this type of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline, and belongs to an automatic valve. The function of the check valve is to prevent the backflow of the medium, the reverse rotation of the pump and its driving motor, and the discharge of the medium in the container. Double-plate check valve is a very common type of check valve. By choosing different materials, the wafer check valve can be applied to water, steam, oil in petrochemical, metallurgy, electric power, light industry, food and other industries. , nitric acid, acetic acid, strong oxidizing medium and urea and other media.

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.
