Fossil Fuel

Providing fossil fuel power plants with severe service ball valves for high temperatures and high pressures.

Process flow diagram showing a typical fossil fueled power plant. Modern fossil fuel plants are highly complex, custom-designed systems. Emerging boiler technologies and progressive system upgrades are increasing plant capacities and changing the operating landscape. These innovations include higher temperatures and pressures found in advanced super-critical and ultra super-critical plants.

At MOGAS, we have partnered with major power producers and have applied aggressive research & development efforts in metallurgy, design and surface coatings to design and manufacture high pressure valves and high temperature valves that answer their specific needs. Because MOGAS is committed to protecting our customer’s critical equipment, continuous product innovation is a vital part of the way we do business.
