The fixed cone valve is mainly composed of valve body, nozzle, sleeve gate, rocker arm, inlet and outlet pipe, drive shaft and floating valve seat. The fixed cone valve water flows into the valve through the valve inlet, increases in the flow path between the fixed dimension and the sleeve, and flows out after passing through the diversion orifice. We often need to perform anti-corrosion coating operations on this kind of valve, so do you know what are the special anti-corrosion coating requirements for fixed cone valves? The special requirements for the anti-corrosion coating of the fixed cone valve are as follows: Requirement 1: Before coating, the valve body should be shot blasted to reach the Sa2.5 level requirement to completely remove the floating rust, grease and attachments. Requirement 2: All valves, operating mechanisms and ancillary equipment should be painted with a protective coating with good water resistance.
