Valve

The valve controls the flow of materials in pipelines (gas, fluids, solid state flows). Shut-off device for fluids, consisting of a housing with a partition wall with circular passage. This is closed by a plug sitting on a stem, which controls the flow. In addition to valves that can only be completely open or closed (open/close valves), there are control valves for controlled influencing of the flow. Valves are operated by a valve actuator.
