Product Details

Semi Lug JIS Butterfly Valve

The main structural features of the lug type turbine butterfly valve are the wafer type and flange type triple eccentric sealing. The valve seat sealing ring adopts two structures of elastic sealing and soft and hard compatible multi-layer sealing. Its sealing performance is reliable to ensure that the butterfly valve is opened. The plate does not touch the sealing seat, which eliminates the uneven load of the sealing seat, prolongs the service life and ensures reliable sealing performance. It has the advantages of high-temperature resistance, wear-resistance and corrosion resistance. It is widely used in pipelines such as petroleum, chemical industry and ships.
