Wafer-style buttefly valves

The wafer style butterfly valve is designed to maintain a seal agasint bi-directional pressure differential to prevent and backflow in systems designed for unidirectional flow. It accomplishes this with a tightly fitting seal ; i.e. gasket, o-ring, precision machined, and a flat valve face on the upstream and down stream side of the valve.
