Avoid Unscheduled Plant Shutdowns with Valve Actuator Diagnostics

Electric motor-operated valve actuators can tell you a lot about their condition. Learn how to take advantage of sophisticated diagnostics available from current designs combined with networking protocols.

Constant diagnostic evaluation of electric motor-operated valves (MOVs) has become an important tool for asset management, predictive maintenance programs, troubleshooting, and scheduled periodic maintenance.

Diagnostic testing of electrically actuated valves began nearly 30 years ago to validate the operability of safety-related MOVs in the nuclear power industry. Since this periodic, manually-initiated form of diagnostic testing could identify problems in both the valve and actuator, it became not only the tool to verify MOV operation, but also for troubleshooting and preventive maintenance.

Today, electric valve actuators served by digital communication networks are commonplace among new plant installations. This is partly due to recent advances in electric actuators that allow them to process more diagnostic information than comparable pneumatic models.

Valve-specific diagnostics allow you to monitor the health of all valves and actuators in a plant or process. By gathering, analyzing, and packaging results inside the electric actuator, you can monitor the valve's health. A valve warning prior to a critical failure gives your maintenance personnel time to repair the valve without unscheduled shutdown and loss of productivity.
