Two-way hard seal disc valve is a new type of butterfly valve carefully developed by our company by comprehensive use of advanced technology at home and abroad and accumulation of many years of professional experience in butterfly valve production. Two-way sealing butterfly valve is mainly used in petroleum, chemical industry, power station, metallurgy, paper making, plumbing, light industry and other fields, as a device for cutting off and regulating the pipeline.
Structural characteristics
Our company’s two-way pressure-bearing butterfly valve not only uses the conventional three-eccentric multi-level hard seal structure, but also combines the movable seat principle of the fixed ball valve, which more effectively guarantees the sealing performance of the reverse pressure-bearing, and truly achieves the two-way pressure-bearing 100%.
