sulgventiili
Sulgventiili, also known as a shut-off valve or isolation valve, is a mechanical device used to control the flow of a fluid within a system. Its primary function is to either completely stop or allow the passage of the fluid. Unlike control valves that modulate flow, sulgventiili are designed for on-off operation. They are commonly found in plumbing, industrial pipelines, and various mechanical systems where the ability to isolate sections for maintenance, repair, or emergency shutdown is crucial.
The operation of a sulgventiili typically involves a movable component that obstructs or opens the flow path.
