Understanding wet steam erosion

Wet steam erosion occurs when condensate droplets travelling at high velocity strike valve internals. During start-up, shutdown and low-load operation, this can rapidly damage trim components, reduce valve performance and increase maintenance requirements. EroSolve Wet Steam is designed to help protect critical valves operating in these challenging conditions.

Trim damage

Continuous exposure to wet steam can wear critical trim components, reducing performance and shortening valve service life.

Steam leakage and passing

Erosion of sealing surfaces can lead to internal leakage, affecting valve efficiency, controllability and reliability.

Increased maintenance costs

More frequent inspection, repair and component replacement can increase maintenance requirements and operating costs.

Reduced plant reliability

Unexpected valve degradation can contribute to unplanned outages, reduced availability and wider operational risks.

How EroSolve Wet Steam protects critical valves


EroSolve Wet Steam is a retrofit solution designed to help combat wet steam erosion in critical steam valve applications. Through purpose-engineered trim upgrades, it helps protect valve internals from the damaging effects of wet steam and condensate, extending equipment life and improving long-term operational reliability. The solution can be applied to existing valves, helping operators address erosion issues without replacing the entire assembly.

Designed to resist erosion

Purpose-engineered sealing surfaces and trim components help protect valves from wet steam erosion and condensate damage.

Extended valve life

Erosion-resistant materials help reduce wear on critical components, extending valve service life and performance.

Upgrade existing assets

Retrofit existing valves without replacing the valve body or actuator, maximising the value of installed equipment.

Simplified maintenance

Upgrade options can reduce maintenance complexity while making future servicing and repairs more straightforward.

Reduced operational risk

Help minimise the effects of wet steam erosion that can contribute to leakage, unplanned maintenance and reliability issues.

Tailored engineering support

Engineering analysis helps identify erosion mechanisms and determine the most effective upgrade approach for each application.

Need to reduce wet steam erosion in bypass valves?

IMI can review wet steam erosion, leakage or trim damage and assess whether an EroSolve Wet Steam upgrade could improve valve life and reduce downtime.
