Szelepállapotok

Szelepállapotok, often translated as valve states or valve conditions, refers to the different operational or functional statuses a valve can be in within a mechanical or fluid system. Understanding these states is crucial for system control, diagnostics, and maintenance. The primary and most fundamental valve state is "open," meaning the valve allows fluid or gas to pass through freely. Conversely, the "closed" state signifies that the valve is preventing any passage.

Beyond these basic states, valves can also be in intermediate positions. A "partially open" or "throttled" state allows for controlled flow regulation, where the amount of substance passing through is restricted to a specific level. This is often used to manage pressure or flow rates. Another important state is "closed tight" or "dead tight," indicating a complete seal with no leakage. This is critical in many applications where even minor leaks are unacceptable.

Valves can also be in a "locked" or "secured" position, preventing accidental operation. This is common in safety-critical systems. In some contexts, "failed open" or "failed closed" are also considered states, describing what happens to the valve in the event of a power loss or system malfunction. These inherent safety features are designed to put the system into a predetermined safe condition. Finally, a valve can be in a "maintenance" or "isolated" state, where it is intentionally taken out of service for repair or inspection. Each of these states has distinct implications for system performance and safety.
