How To Use Sanitary Butterfly Valve In Marine Environment

In the marine environment, the corrosion of Sanitary Butterfly Valve is much greater than that on land, because the evaporation of seawater will cause some salt to accumulate on the surface of the butterfly valve, so we need to perform surface anti-corrosion treatment on this part of the sanitary butterfly valve.

The caliber of the sanitary butterfly valve is generally calculated according to the flow rate of the pipeline medium. If you want to correctly select the caliber of the sanitary butterfly valve, you should first calculate the pipeline flow rate. In the general flow calculation process, the flow coefficient of the valve can be divided into the rated flow coefficient and the operating flow coefficient. The rated flow coefficient is an inherent characteristic of the valve. As long as the valve structure is determined, the rated flow coefficient will be determined accordingly, regardless of the temperature, pressure, density, etc. of the operating conditions. The operating flow coefficient is determined by the (large, normal, small) flow rate of the operating conditions and the corresponding working temperature, valve front pressure, valve back pressure, medium density and other parameters, and has nothing to do with the valve structure.
