Sedelon Valve Painting Standard
Different engineering environments and corrosion classes have different standards for valve painting.
Sedelon valve painting standard is as follows:

Usually, except for carbon steel material(WCB, LCB, etc.), valves material of stainless steel, bronze and other materials do not need to be painted due to themselves are corrosion-resistant.
In addition, Sedelon can customize the valve painting color according to customer requirements.
The following are various valves with different painting colors for your reference.
