As a foundry-based source manufacturer, we control every step from casting to assembly. Backed by 20+ years of proven performance, we build valves that directly enhance plant availability and thermal efficiency.
Explore Power Generation SolutionsA modern power plant's profitability hinges on overcoming three core operational threats. Our valves are specifically engineered to conquer each one.
High-pressure steam cycles induce extreme thermal shock and high-cycle fatigue, leading to seat leakage, stem failure, and catastrophic pressure boundary breaches.
Flue Gas Desulfurization (FGD) slurries, cooling water intake, and water treatment chemicals cause rapid erosion and corrosion, destroying seals and seizing valves.
Even minor seat leakage in steam or feedwater lines directly impacts plant heat rate and fuel cost. A critical valve failure leads to forced outages costing millions per day.
Instantly match your power plant system to our recommended valve architecture. For detailed specifications, see the performance tiers below.
| Performance Tier | Application System | Recommended Valve Architecture | Key Material Specs |
|---|---|---|---|
| Critical Path & Steam Cycle | Main Steam Isolation, BFW, Turbine Bypass | Triple Offset | A216 WCB/WCC, A217 WC6/WC9 |
| Balance of Plant & Severe Service | FGD Slurry, Condenser Isolation | Metal Seated / Rubber Lined | Duplex SS, Hard Faced, EPDM |
| Ancillary & Utility Systems | Firewater, Water Treatment, HVAC | Resilient Seated (Bi-Directional) | Ductile Iron, SS Disc, EPDM/NBR |
Select the right valve based on the system's impact on plant uptime and efficiency. Our engineers are ready to configure a solution for your exact operating parameters.
For high-pressure, high-temperature applications where absolute zero-leakage and reliability are non-negotiable to ensure plant safety and efficiency.
The definitive choice for critical steam and water isolation. The non-frictional, torque-seated design provides repeatable, bubble-tight shutoff even after severe thermal cycling, protecting plant efficiency and preventing outages.
View Steam-Rated SpecsA robust solution for medium-pressure steam and critical water systems. The double-offset design with advanced seat materials provides superior sealing and durability compared to conventional valves in demanding services.
View SpecificationsEngineered solutions for large-diameter, abrasive, or corrosive applications that are crucial for plant operation but sit outside the primary steam cycle.
The optimal solution for large-diameter cooling water lines. A thick, field-replaceable EPDM or NBR liner provides bi-directional, drip-tight sealing and protects the valve body from corrosion and biofouling. Available in very large dimensions.
View Large Diameter SpecsDesigned to survive highly abrasive services like FGD limestone and gypsum slurries. Hard-faced (e.g., Stellite) seat and disc construction resists erosion, ensuring long service life and reliable shutoff where soft-seated valves would fail in hours.
View Abrasion-Resistant SpecsDependable and cost-effective valves for all essential plant support systems, built to a higher standard of quality for long, maintenance-free service.
More than a commodity valve, it's an asset. Our proprietary seat design delivers reliable, bi-directional bubble-tight shutoff, eliminating leaks that can compromise essential plant support systems.
View Utility Valve SpecsIdeal for corrosive chemical handling in water treatment systems. A fully isolating liner provides maximum corrosion resistance at a fraction of the cost of exotic alloy valves, guaranteed by our in-house quality control.
View Chemical SpecsPlant reliability isn't a feature; it's a result of total manufacturing control. By integrating the entire process from casting to final testing, we eliminate the variables that cause valve failure and force plant outages.
Our casting heritage, led by material experts, ensures every high-temp alloy (like A217 WC6/WC9) has the precise chemistry and heat treatment needed for superior creep resistance and thermal stability.
Our 11 CNC centers machine components to strict dimensional standards. This is critical for achieving the repeatable, zero-leakage metal-to-metal sealing required in high-pressure steam service.
Our valve designs aren't theoretical. They have been refined and validated over 20+ years in the most demanding power plant applications, giving you unparalleled assurance of long-term operational reliability.
