Sanitary Butterfly Valve Precautions for use in marine environment

In marine environment, the corrosion of sanitary butterfly valves 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 sanitary butterfly valves.

The caliber of sanitary butterfly valves is generally calculated according to the flow rate of pipeline media. If you want to correctly select the caliber of sanitary butterfly valves, 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 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.
