Brief Introduction:
The structure of wafer type butterfly valve can be middle line, double offset and triple offset. These types of butterfly valves are widely used in water source projects, urban water supply and drainage, sewage treatment, electric power, petroleum, petrochemical, heat supply, shipbuilding, medicine and metallurgy industries. Valves used for regulating or cutting off liquids in pipelines.
Design Features
Design standard as per: API 609, ASME B16.34, GB/T12238, JB/T 8527.
Small installation space, light weight, and maintenance friendly; High reliability of strength and rigidity.
Good sealing effect and long service life without leakage.
The sealing ring could be replaced on pipeline without removing the valve
Small friction of seat and torque during opening or closing,
Good flow adjusting ability, high precision of flow characteristic curve and good dynamic adjustment stability;
For soft seat the leakage rate: ANSI B 16.104 Ⅵ.
