Seris 13 Wafer Type DI Butterfly Valve Lever Opreation

Wafer type butterfly valve

1. PROFUCT PROFILE

Wafer type butterfly valve is one type of central lined butterfly valve, which is one normal type of butterfly valve in need of big quantity. It is mounted between two matching flanges of the piping with bolts & nuts.The wafer style butterfly valve is designed to maintain a seal against bi-directional pressure differential to prevent any 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 downstream sides of the valve. Prosper Flow can produce the wafer butterfly valve rubber lined in accordance with EN593, API609 and AMSE B16.34.
