Metal-Seated Ball Valves & Bellows Seal Valves for Power Generation Projects
High-Torque Pneumatic Actuators | Customizable for Industrial Applications
In power generation projects, valves routinely operate under severe service conditions, including high temperatures, high pressures, elevated differential pressures, frequent cycling, and harsh erosion. Different types of power plants—such as thermal, nuclear, hydroelectric, combined cycle, and geothermal—have specialized requirements for valve sizing, material selection, and performance.
Core Application & Functionality: Power generation facilities rely heavily on ball valves to ensure rapid, high-integrity isolation across steam, water, fuel, and auxiliary systems.SJ Metal-seated ball valves are mandated for high-temperature steam applications to overcome the thermal degradation limits of soft polymer seats. Metal seats maintain tight shut-off integrity (adhering to permissible seat leakage classes) while resisting severe erosion caused by wet or high-velocity steam flows.
