Power Generation Valves

Engineered for Extreme Thermal & Pressure Stress

Modern power generation pushes materials to their physical limits. VALVA addresses these high-stakes challenges with precision engineering:

• High-Temperature Stability: Materials like 310S, Inconel, and Hastelloy that maintain structural integrity above 600°C – 1000°C.
• Creep Resistance: Engineered to prevent metal deformation over decades of continuous high-heat service.
• Zero Leakage Performance: High-pressure Gate and Globe valves designed to ensure tight shut-off in critical steam lines.
• Corrosion & Erosion Defense: Protecting against “Steam Cutting” and chemical corrosion in boiler feed water systems.

Solutions Across the Energy Spectrum

We provide specialized valves for a wide variety of power generation technologies:

1. Thermal Power (Coal & Gas): High-pressure valves for main steam lines, reheaters, and boiler feed water systems.
2. Nuclear Power: Valves manufactured to the highest safety standards for cooling systems and waste steam boilers (utilizing Inconel 600/625).
3. Combined Cycle (CCGT): Optimized solutions for Heat Recovery Steam Generators (HRSG).
4. Renewable Energy: Specialized valves for Geothermal brine handling and Concentrated Solar Power (CSP) molten salt systems.
5. Hydroelectric: Large-scale isolation valves designed for high-velocity water flow and reliable operation.

Optimized Metallurgy for Power Excellence

Choosing the right alloy is the difference between a 20-year lifespan and a catastrophic failure.

Application	Recommended Material	Why it Works
Supercritical Steam	Stainless Steel 310S / 904L	Superior oxidation and high-temperature creep resistance.
Nuclear Steam Boilers	Inconel 625 / 600	Exceptional resistance to stress corrosion in high-temp water.
Geothermal Brine	Titanium / Duplex 2507	Withstands highly abrasive and corrosive underground fluids.
Cooling Systems	Nickel-Aluminum Bronze	Best for seawater cooling circuits in coastal power plants.

Rigorous Standards for Power Safety

At VALVA, we understand that in power generation, there is no room for error:

• Design Compliance: ASME B16.34 (High Pressure/Temp), API 600, and ASME Section III (for nuclear-related components).
• Testing & Inspection: Extensive Non-Destructive Testing (NDT), including Radiographic (RT) and Ultrasonic (UT) testing.
• Surface Integrity: Hard-facing (Stellite) on seats and discs to prevent wear in high-frequency cycling.
• Certifications: Full traceability with MTR 3.1, CE/PED, and ISO 9001 compliance.
