The Hidden Backbone of Every Energy Plant
Every energy plant is, at its core, a system of controlled flows, and every flow depends on industrial valve manufacturers who build components that can withstand extreme pressures, temperatures, and corrosive media for decades without failure.
These flows include steam, condensate, heat transfer fluid, cooling water, compressed air, and fuel gas. Each of these circuits relies on valves to start, stop, regulate, and protect the process. Each of these circuits relies on valves to start, stop, regulate, and protect the process.
However, across our experience with 18+ global energy projects, valve-related issues remain one of the most underestimated contributors to unplanned downtime, energy losses, and safety incidents.
In practice, a single valve failure has the potential to bring an entire plant to a standstill, whereas a well-selected valve, engineered to the correct specifications and maintained appropriately, can deliver reliable performance for decades with minimal or no intervention.
At EOM Energy, our field engineers work with valve systems daily, from high-pressure steam isolation in thermal power plants to molten salt circuit control in CSP facilities and HTF regulation in solar thermal loops.
For this reason, this guide brings together that experience as a practical reference for O&M teams, procurement engineers, and asset owners, including a selection of industrial valve manufacturers relevant to the energy and industrial sectors.
Why Valves Deserve More Attention in Your O&M Strategy
Most maintenance strategies treat valves as passive components, considering them as items on a preventive maintenance checklist that are exercised once a year and then largely ignored. This approach is fundamentally flawed.
A typical thermal power plant contains anywhere from 2,000 to more than 10,000 valves, spanning dozens of types, materials, pressure classes, and actuation methods. As a result, each one represents a potential failure point. Unlike rotating equipment, where vibration monitoring and oil analysis provide early warning, valve degradation is often silent until it becomes critical.
Common Valve Failure Modes in Energy Plants
Valve failures can manifest in several ways. The most common include:

How EOM Energy Supports Valve Management in Energy Plants
Valve selection, specification, and maintenance are core competencies within EOM’s Maintenance Technical Services and Operational Consulting divisions. Our team supports clients with:
- Valve criticality assessment — Identifying which valves carry the highest consequence of failure and prioritizing maintenance resources accordingly.
- Maintenance strategy optimization – Integration of valve maintenance into the overall reliability program, including CMMS/EAM configuration for valve-specific work orders.
- Outage planning and valve overhaul supervision — Ensuring valve work during shutdowns is scoped correctly, executed to specification, and validated before return to service.
- Spare parts strategy — Analysis of valve inventory to identify critical spares, standardization opportunities, and supply chain risks.
- O&M procedure development — Writing clear, plant-specific valve operating and maintenance procedures that reflect actual field conditions.
