Double hale-stem butterfly valve is single and compact in structure and light in weight, and easy for assembly and disassembly

Operating torque of it is small, then tuning 90(it can open or close with light and fast action)

Small in flowing resistance and good in energy-saving effect, with discharge characteristic approximating inclined straight line

Featured by reliable sealing, zero leakage with ten thousands of opening and closing time

Valve can be made of various materials, adapted to all kinds of media

Used in the pipeline and vessels for conveyingvarious corrosive and non-corrosive fluid media in the engineering systems of water supply, generating, petroleum, gas, environmental protection and also for regulating and cutting off the off the flowing of media
