• ✓ Service-friendly construction: Designed for quick access and minimal downtime during maintenance
• ✓ Proven in extreme conditions: Reliable in supercritical and ultra-supercritical thermal systems

HP/IP/LP Bypass Valves

Engineered for rapid steam pressure and temperature control, HP, IP, and LP bypass valves are critical for safe turbine startup, shutdown, and load changes. These valves are designed to operate reliably under extreme conditions, ensuring system stability and efficiency.

Their robust construction and advanced trim designs minimize noise, erosion, and thermal stress, making them indispensable for modern power generation plants where reliability and responsiveness are non-negotiable.

Reheater Safety Valves

Designed for fail-safe overpressure protection, reheater safety valves respond instantly to thermal or pressure excursions, safeguarding critical reheater and boiler components.

Built for extreme temperature fluctuations and frequent cycling, these valves ensure compliance with safety standards while providing years of reliable service in high-demand environments.

Special Service & Auxiliary Valves

Special service and auxiliary valves are custom-engineered to meet unique operational challenges such as high cavitation risk, abrasive media, or extreme thermal cycling.

These valves are often deployed in auxiliary steam, start-up bypass, or specialized process control duties where standard valve designs may not perform optimally. By tailoring materials, trims, and actuation methods to the specific service conditions, they ensure maximum reliability, safety, and efficiency over extended service life.
