Features

The valve plate of the wafer type check valve is fixed on the valve body along a pivot, and the two springs are arranged on the valve plate above the sealing surface. Under the pressure of the medium flow pressure, the spring is pressed to force the valve plate to open. When the medium is reversed, the spring forces the valve to close. This valve can be fitted on both horizontal and vertical lines.
