No one pays attention to ball and plug valves — until they stick, which can cause process fluids to be lost, product damaged, energy wasted, even danger to personnel.

 

Sticking valves are as common as the method generally used to "fix" them: a blow from a hammer, which usually damages the valve in the attempt to unstick it.

 

A better solution is to prevent the problem from occurring in the first place — with a thin coating of Xylan (25 microns/0.001 in.). Xylan has been used on plug and ball valves for more than thirty years to provide insurance that the valve will work when it must.
