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.

Connections for pneumatic control lines to valves in food, beverage, chemical and pharmaceutical plants are exposed to very high loads; in addition to functionality, ease of installation and dependability, the materials used for the connections must be as durable as the valves themselves. Series 17 of the Eisele INOXLINE features impressive quality and workmanship. These stainless steel push-in connectors provide a lasting and reliable seal even in humid environments. The material also features good hygienic properties.Read more
