double eccentric butterfly valve
The wafer style butterfly valve is designed to maintain a seal against bi-directional pressure differential to prevent 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.
Features and benefits
The butterfly valve is a new generation of product carefully developed through assimilating and digesting foreign technologies and combining suggestions of domestic users and experience accumaulated during production.
