Turbine flange type titanium butterfly valve is used in aqua regia and sodium hypochlorite. Chlorine water, wet chlorine and other media have good corrosion resistance. The corrosion resistance of titanium in organic acids depends on the reduction or oxidation of the acid. When the turbine flange titanium butterfly valve is used under special working conditions, such as throttling regulation, strict sealing requirements, or severe wear, low temperature (cryogenic) and other working conditions, it is necessary to use the special butterfly valve with three eccentricities or double eccentricities of the specially designed metal sealing belt regulating device.

Turbine flange titanium butterfly valve is a three-dimensional eccentric metal sealing structure, and the sealing type is metal to metal sealing. The special sealing system of turbine flange titanium butterfly valve can ensure high sealing performance in all temperature ranges from ultra-low temperature to ultra-high temperature.

The turbine flange titanium butterfly valve produced by Shanghai Yinsha is widely used in chlor alkali industry, soda ash industry, pharmaceutical industry, chemical fertilizer industry, fine chemical industry, textile fiber synthesis and bleaching and dyeing industry, basic organic acid and inorganic salt production, nitric acid industry, etc.
