Why the valve is Galvanized Plating,Cadmium plating,Chrome Plating,Nickel plating
Galvanized Plating Zinc is relatively stable in dry air and is not easy to change color. In water and humid atmosphere, it reacts with oxygen or carbon dioxide to form oxide or alkaline zinc carbonate film, which can prevent zinc from continuing to be oxidized and play a protective role. Zinc is ...Read more -
Why do valve surfaces need coatings
Corrosion is one of the important elements that cause valve damage. In valve protection, valve corrosion protection is an important issue to consider. For metal valves, surface coating treatment is the best cost-effective protection method. 1. Shielding After the metal surface is coated with pain...Read more -
What is The Difference Between Triple Eccentric Butterfly Valve, Double Eccentric Butterfly Valve, Single Eccentric Butterfly Valve And Centerline Butterfly Valve
