Revolutionizing Valve Maintenance
In industrial operations, ensuring reliability and reducing downtime are non-negotiable goals for maintenance teams. Emerson’s FIELDVUE™ Digital Valve Controllers, equipped with “The Big Three” diagnostics, offer a transformative approach to achieving operational excellence. These diagnostics—Supply Pressure Alert, Drive Signal Alert, and Travel Deviation Alert—are tailored to provide deep insights into process health, enabling teams to detect potential issues before they escalate and optimize overall plant performance.
“The Big Three” diagnostics empower maintenance teams to confidently transition from reactive to proactive maintenance, addressing key operational challenges while ensuring long-term equipment reliability.
What Are “The Big Three” Diagnostics?
“The Big Three” diagnostics work seamlessly together to provide a comprehensive picture of valve performance:
- Supply Pressure Alert monitors the air or gas pressure supplied to the valve actuator. By detecting fluctuations or drops in pressure, it ensures stable actuator operation, preventing performance disruptions.
- Drive Signal Alert tracks the input control signal received by the DVC, detecting deviations or interruptions caused by faulty wiring, signal interference, or controller issues. This ensures smooth communication between the Distributed Control System (DCS) and the valve, enabling precise and reliable operation.
- Travel Deviation Alert compares the commanded valve position to its actual position, identifying discrepancies caused by sticking, wear, or actuator issues. This insight allows for timely interventions, preventing costly process inefficiencies.
These diagnostics are a powerful combination that ensures maintenance teams have the tools they need to address problems early and safeguard critical processes.
Success Stories: Practical Benefits of “The Big Three”
Enhancing Stability in the Chemical Industry
During a major shutdown at a leading chemical production facility, “The Big Three” diagnostics proved instrumental. The Supply Pressure Alert identified fluctuating air pressure in valve actuators, allowing the maintenance team to quickly stabilize operations. Simultaneously, the Travel Deviation Alert highlighted minor misalignments in valve positions, enabling corrections that restored optimal performance.
Ramesh Tamilarasu, an Emerson Manager in Qatar, shared that this approach involved the diagnostic evaluation and optimization of 20 valves in a single cycle, delivering measurable results. By implementing “The Big Three” diagnostics, the facility reduced valve-related disruptions by approximately 30%, decreased maintenance costs by an estimated 20%, and improved overall system reliability, contributing to a significant increase in operational uptime. With operations back online faster than anticipated and running with enhanced reliability, the chemical production facility ensured consistent performance across critical systems, directly impacting the plant’s bottom line.
Preventing Downtime in the Energy Sector
In a prominent energy production plant, intermittent disruptions in control signals threatened operational efficiency. The Drive Signal Alert detected irregularities caused by faulty wiring, preventing what could have been a significant downtime event. Additionally, the Travel Deviation Alert identified sticking issues in several valves, allowing targeted maintenance during planned shutdowns.
These proactive measures not only resolved immediate issues but also ensured smoother, more consistent operations moving forward.
Creating Value in the Manufacturing Sector
In one notable case within the manufacturing sector, health checks powered by “The Big Three” diagnostics revealed inefficiencies that were subsequently addressed through lifecycle management solutions. This approach improved system reliability and showcased the measurable benefits of proactive diagnostics, reinforcing long-term customer trust and operational success.
