Coatings are available which can provide suitable protection to valves and actuators, both internally and externally, in even the severest of applications.
A valve is a device that regulates, or controls the flow of a fluid (gases, liquids, or slurries) by opening, closing, or partially obstructing various passageways. In an open valve, fluid flows in a direction from higher pressure to lower pressure. Valves have many uses, including controlling water for irrigation, industrial uses for controlling processes, residential uses such as on/off and pressure control to dishwashers and washing machines for clothes as well as water taps in the home. Valves are also used in the military and transport sectors. In HVAC ductwork and other near-atmospheric air flows, the role of valves is more like a damper.
