Thermal and coal-fired power plants operate under some of the most demanding conditions in industrial processing. High-pressure steam, hot condensate, cooling water, and abrasive ash handling systems all place heavy stress on valves and sealing components. In many older plants, standard valves struggle to maintain stable performance over long operating cycles, especially in high-temperature or erosion-prone areas.
Power plant operators often encounter recurring problems such as seat wear, internal leakage, cavitation damage, or actuator failure around boiler feedwater systems and steam isolation lines. In ash slurry applications, erosion can become particularly severe when conventional valve materials are used. Because of this, many facilities now prefer OEM or ODM valve solutions designed specifically for their operating conditions.
Why Custom Valve Design Matters
OEM valve manufacturing is commonly used when plants need replacement valves built to existing pipeline dimensions and pressure ratings. This approach is practical for maintenance projects where system layouts cannot easily be modified.
ODM projects usually involve a higher level of engineering support. In these cases, valve manufacturers work together with plant engineers to improve flow control performance, reduce maintenance frequency, or solve recurring reliability problems. Depending on the application, upgrades may include improved trim materials, modified sealing structures, anti-cavitation designs, or special coatings for high-temperature service.
For ash handling and slurry transport systems, operators may also request hardened internal components or metal-seated valve designs to improve resistance to abrasion. In steam systems, alloy materials such as WC9 or C12A are often selected for high-temperature durability.

Selecting the Right OEM & ODM Valve Supplier
In thermal power applications, valve reliability is closely connected to plant safety and operational stability. Beyond manufacturing capability, buyers should also evaluate material traceability, pressure testing procedures, and quality documentation before placing large orders.
Many power plants require hydrostatic testing, seat leakage inspection, and fugitive emission verification before installation. International engineering standards and guidance from organizations such as the Electric Power Research Institute (EPRI) can also help operators improve valve selection and maintenance planning.
As aging thermal power infrastructure continues requiring upgrades worldwide, demand for customized OEM & ODM industrial valves is expected to remain strong in both retrofit and new-build projects.
