The handle of butterfly valve
Manaul metal hard seal butterfly valve is suitable for water, air, natural gas and other media, leak rate is in line with GB/T13927-92 standard, the drive mode is manual, electric, pneumatic, hydraulic.
1, compact structure, small size, light weight, flexible operation, small opening and closing torque, saving energy.
2. The three-eccentric cone angle structure between the sealing pairs enables the two sealing surfaces to disengage from each other immediately when the butterfly valve is opened, ensuring that the sealing pairs do not have friction with each other.
3. The three-eccentric structure between the sealing pairs makes the valve more closed and tighter when the valve is closed. The seal is more reliable and does not leak, and it has a two-way sealing function.
4, high temperature, high pressure, corrosion resistance, long service life, enjoy the reputation of "the same with the pipeline life."
5, with the sealing adjustment performance, the sealing performance is reduced, the sealing ring can be adjusted close to the valve seat, you can restore the sealing performance.
6. When working conditions are required, the function of adjusting the flow rate can be achieved by adjusting the opening and closing angle of the butterfly valve.
The manual clamping type metal hard-seal butterfly valve adopts foreign advanced
