What type of coating is used for valves?
One type of coating applied via HVOF is tungsten carbide (WC). HVOF carbide coatings feature a mechanical bond, in contrast to spray and fuse, or weld overlays, which achieve a metallurgical bond. Tungsten carbide coatings can handle high temperatures and provide toughness; they are useful in combatting against abrasion, erosion and corrosion. Depending on the properties of the valve’s service, different coatings will work. More than likely, you will not start with the hardest tungsten carbide coating matrix, but you may realize that the corrosion chemistry of the service requires another type of coating. The corrosion chemistry can be changed by adjusting the matrix without sacrificing any of the abrasion resistance or hardness because the tungsten carbide is still present.

Why do ball valves leak?
Reasons a Ball Valve Leaks Internally 1 Improper transportation or hoisting damage to the integral valve can lead to the ball valve leaking internally. 2 If the ball valve is not dry before leaving the factory, the sealing surface can corrode with rust and leak. 3 If the safeguard is not implemented correctly at the construction site, rainwater and debris can get into the valve, causing leakage. 4 If no grease is injected into the valve seat during installation, impurities can enter the valve seat, causing internal leakage. 5 If the valve is not in the full open position when installed and welded, this can damage the ball. If there is weld splatter in the switch, it will damage the valve seat, and this will form internal leaking. 6 If the limit isn’t accurate during installation or the stem’s drive is misaligned, the valve will leak.
