Power Generation
Steam circuits punish valves with high temperatures, pressure transients and constant thermal cycling. Our pressure-seal gates, globes and non-slam check valves are specified for main steam, feedwater and extraction lines where shutdown is not an option.

The challenges
- Sustained high-temperature steam service
- Thermal cycling and pressure transients
- Water hammer on pump trip
- Decades-long service life expectations
How Valvax answers
- Pressure-seal gate and globe valves for Class 600–2500 steam duty
- Non-slam axial flow check valves that eliminate water hammer
- Chrome-moly (WC6/WC9) body materials for elevated temperatures
- Forged compact valves for high-pressure drains and vents
Typical applications
Specified For This Duty
Recommended valves for power generation
Pressure Seal Gate Valve – Class 900 / 1500 / 2500
ASME B16.34 pressure-seal bonnet gate valve for extreme-pressure service. The pressure-seal bonnet design ensures tighter sealing as line pressure increases, ideal for high-pressure steam and process gas.
View detailsPressure Seal Globe Valve – Class 900 / 1500 / 2500
ASME B16.34 pressure-seal globe valve for extreme service. Butt-weld ends with GRAFOIL gasket and self-sealing bonnet ensure performance at the highest operating pressures.
View detailsAxial Flow Non-Slam Check Valve
API 6D axial-flow non-slam check valve with soft seat and metal-to-metal seating options. Spring-loaded diffuser disc closes before flow reversal, eliminating water hammer completely.
View detailsForged Globe Valve – Class 800 / 1500 / 2500
API 602 / ISO 15761 forged steel globe valve for precision throttling and isolation in small-bore, high-pressure service. Bolted and welded bonnet variants with NPT/socket weld/BW ends.
