Description
Product Description
Fisher TBX valves play a critical role in power plant operations by simultaneously reducing steam pressure and temperature, enabling safe and efficient daily cycling. They also provide essential protection for key components—such as reheater tubes, condensers, and piping—preventing damage from excessive pressure, temperature, and enthalpy excursions during steam turbine trips. This ensures reliable performance and extends equipment lifespan in dynamic power generation environments.

Features
-
The valve integrates both pressure and temperature control into a single unit, simplifying system design while ensuring precise regulation of steam conditions.
-
Its rugged cage-guided construction allows it to withstand the full pressure drop of main steam lines, making it ideal for high-demand applications.
-
Advanced noise-reduction technology, including Whisper Trim III and WhisperFlo trims, reduces operational noise by 30 to 40 dBA, improving workplace safety and comfort.
-
With the Fisher Bore Seal trim, the valve achieves Class V shutoff even at extreme temperatures up to 593°C (1100°F), thanks to its proven balanced design.
-
The FEA-optimized valve body minimizes thermal stress, ensuring reliable performance in the most challenging operating conditions.
-
Designed for easy maintenance, the valve supports vertical stem orientation in most installations, simplifying access and servicing.
-
Durability is enhanced by a case-hardened cage that accommodates thermal expansion, along with cobalt-based overlays on the plug for wear resistance and tight metal-to-metal sealing.
