Preventive Maintenance vs Predictive Maintenance

The Economic Impact of Predictive Maintenance Capable Solenoid Valves

Preventive maintenance (PM) versus predictive maintenance (PdM), the economic advantages become even more pronounced when considering specific cases such as ultra-critical operations. Take, for instance, the case of predictive maintenance capable solenoid valves:

Cost-Efficiency:

In ultra-critical operations where a single failure can result in substantial losses (over 10L), utilizing predictive maintenance capable solenoid valves becomes a game-changer.

The savings generated over time by avoiding unexpected failures can be tremendous, justifying the initial investment in sophisticated condition-monitoring tools.

Resource Optimization:

Industry standards often dictate the replacement or servicing of valves every 3 years, involving skilled manpower and a significant time investment (30 min to 1 hr) for each valve.

Predictive maintenance capable solenoid valves, with their ability to anticipate issues, minimize the need for frequent manual inspections and interventions, optimizing skilled manpower resources.

Extended Equipment Life:

Traditional PM activities may lead to the unnecessary replacement of valves every 3 years, costing around 25K per valve over its lifetime.

Utilizing PdM can extend the complete life of solenoid valves beyond 10 years, resulting in substantial savings and a more sustainable use of resources.

Reduced Downtime:

With PdM, the need for frequent PM can be significantly reduced. Extending PM intervals from yearly to biennially can substantially increase plant uptime, translating to 5 – 10 days of additional revenue.

The ability to detect and address issues before they lead to failures enhances overall plant productivity and reduces downtime-related losses.

Safety:

Early detection through PdM not only saves costs but also enhances workplace safety by preventing unexpected equipment failures that could pose risks to personnel and assets.

Inventory Management:

PdM anticipates part failures, allowing for precise inventory management. Rather than carrying heavy inventories of parts or spares, one can order replacements once signs of failure are detected, optimizing inventory costs.

In conclusion, the adoption of predictive maintenance capable solenoid valves goes beyond immediate cost savings, offering a strategic advantage by enhancing safety, optimizing resources, and prolonging the overall life of critical equipment. For industries where downtime and efficiency are paramount, the shift towards predictive maintenance becomes a compelling proposition.
