Lug butterfly valve for high pressure is mainly composed of a backless structure body, an integrated stem, and a streamlined plate. The rotation of actuating device makes stem and disc revolved, which ensures on-off operations and flow control. The rotation of actuating device ensures dependability and position disc control. Rotate the handle wheel clockwise, the valve is closed.
The overall structure of this type valve is simple, the installation and operation are convenient, the sealing performance is good, the service life is long, and the reliability is high.
▪Compared with wafer butterfly valves, lug butterfly valves have better stability
▪lug butterfly valve can be configured with pneumatic, electric, hydraulic, manual devices according to customer’s requirement to meet the needs of remote control and program control
▪Compared to gate valve, butterfly valve is small size, occupy small space
▪The butterfly valve has two seal types: resilient seal and metal seal. resilient seal butterfly valve, seal ring can be inlaid on the valve body or attached to the butterfly plate around, resilient seal butterfly valve has good seal performance
▪The lining can be replaced with good anti-corrosion materials, which can adapt to corrosive, strong acid medium
