valve-but

A valve is a device that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically valves fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word is derived from the latin valva, the moving part of a door, in turn from volvere, to turn, roll.

Types Of Valves:

We are experienced to supply valves in piping projects in many industries can be provided several kinds, such as:

  • Ball Valves
