Power Generation Valve Solutions

Engineered for fly ash, boiler feedwater, slurries, and steam — the severe-service applications that keep utility-scale and industrial power facilities running every hour of every day.

The Industry

Engineered for the Toughest Operating Conditions

Power generation facilities — whether coal-fired, combined-cycle, nuclear, biomass, or industrial cogeneration — operate under some of the most demanding conditions in industry. Abrasive fly ash, high-temperature steam, slurry transport, and the relentless need for uptime mean valve failures aren't just expensive — they're operationally catastrophic.

For three decades, Miller Valve & Controls has supplied power generation customers with severe-service valves engineered to survive the conditions and deliver reliable performance year after year. From utility-scale plants to industrial cogeneration, our valve solutions handle the specific challenges of each application — fly ash erosion, boiler feedwater pressures, steam thermal cycling, and slurry abrasion.

We work closely with plant engineers, EPC firms, and maintenance teams to spec the right valve, the right material, and the right actuation for each application — backed by the manufacturer partnerships and engineering experience that come from 30+ years in the field.

Common Applications

Where Our Valves Earn Their Keep

Every power gen application has its own demands. Here's how we approach the most common — and the valve types we recommend for each.

Fly Ash Handling

Urethane-lined knife gate valves with replaceable wear sleeves resist abrasive ash particles in pneumatic conveying systems. Zero-leakage designs for long service life.

Boiler Feedwater

High-pressure ball valves and globe control valves with forged bodies and hardened trims. Reliable shutoff for makeup, recirculation, and feedwater regulation lines.

Cooling Water

Large-diameter butterfly and ball valves for circulating water systems. Available in carbon steel, stainless, and exotic alloys for both freshwater and seawater service.

Makeup & Return Water

Utility valves for water treatment, demineralization, and condensate return. Reliable isolation and control for the auxiliary systems that keep your plant operating.

Steam Service

Metal-seated ball valves and high-temperature globe valves for main steam, auxiliary steam, and steam condensate. Designed for thermal cycling and zero-leakage shutoff.

Dewatering Systems

Knife gate valves engineered for slurry dewatering, ash slurry pumping, and bottom ash handling — fully repairable in-line and built for solids-laden flows.

Slurry Service

Urethane-lined and metal-seated valves for fly ash slurry, bottom ash slurry, and gypsum slurry — engineered for zero leakage in the most abrasive applications.

Powder Handling

Specialty knife gate valves for fly ash conveying, lime injection, and pulverized coal handling. Quick-acting designs that resist plugging and packing.

Vendor Partners

Trusted Manufacturers for Power Gen

Our power generation valve solutions draw from a curated set of manufacturer partnerships — chosen for their materials science, engineering depth, and field-proven reliability.
