Process and Control Valves for Fluid Handling
Fluid handling valves are used for controlling the flow of liquids, gases and slurries in a pipe or other enclosure, as directed by a signal from a controller. Control valves enable the direct control of flow rates of fluids, therefore controlling process quantities such fluid level, temperature and pressure.
Control of the valves is by means of a movable element that opens, shuts, or (partially) obstructs an opening in a passageway. Fluid process valves are of seven main types: gate valves, globe valves, plug valves, needle valves, butterfly valves, spool valves and poppet valves. This Technology Zone offers an insight into the latest innovations in fluid processing and control valves.
