Regulations
Business Context
Emergency shutdown valves, isolation valves, and other final elements
must operate reliably whenever demanded. Frequent operation improves
confidence that these devices remain functional but also increases
mechanical wear and maintenance requirements.
The Contradiction
More frequent operation verifies equipment readiness.
Less frequent operation extends equipment life.
Why It Exists
Final elements are designed primarily for emergency demand rather than
continuous operation, making routine verification essential while
simultaneously contributing to component wear.
Direction
Use partial stroke testing, condition monitoring, and intelligent
diagnostics to verify valve performance while minimizing unnecessary
mechanical movement.
