We are a foundry-based source manufacturer, integrating casting, precision machining, and assembly. Led by material science experts and proven over 20 years, we deliver valves where failure is not an option.
Explore Engineered SolutionsA successful valve must master three distinct threats. Failure in any one area leads to catastrophic safety, environmental, and financial consequences.
Leakage of hazardous or flammable media poses immediate risks to personnel, environmental compliance (EPA), and profitability through product loss.
Extreme temperatures (cryogenic to 600°C+) and aggressive chemical corrosion cause embrittlement, seal failure, and rapid degradation of standard materials.
In a continuous process plant, a single valve failure can trigger a full shutdown, resulting in immense production losses and high emergency repair costs.
Instantly match your process challenge to our recommended valve architecture. For detailed specifications, see the performance tiers below.
| Performance Tier | Primary Challenge | Recommended Valve Architecture | Key Material Specs |
|---|---|---|---|
| Critical Process & Safety | Fugitive Emissions, High-Cycle Isolation | Triple Offset / High Performance | A105/LF2, CF8M, Duplex, Monel |
| Severe Service & Speciality | Cryogenic Temps, High Temps, Abrasives | Extended Bonnet / Metal Seated | LCB/LCC, WC6/WC9, Hard Faced |
| General & Utility Service | Aggressive Corrosion, General Purpose | PTFE/PFA Lined / Resilient Seated | PTFE, PFA, EPDM, NBR, FKM |
Our 20+ years of field data inform a tiered approach to valve selection. If your requirements are unique, our in-house engineering and manufacturing capabilities allow us to build a custom solution from the ground up.
For hazardous media, high-cycle isolation, and applications where absolute, verifiable zero-leakage is mandatory for safety and environmental compliance.
The ultimate process isolation valve. The torque-seated, friction-free design ensures bi-directional, bubble-tight shutoff (ISO 5208 Rate A) over thousands of cycles, making it the superior choice for critical applications.
View SpecificationsA robust, double-offset design providing excellent sealing and lower torque than conventional valves. A highly reliable and cost-effective solution for less severe but still critical high-pressure and high-temperature services.
View SpecificationsEngineered solutions for applications outside of standard temperature and media ranges, including cryogenic, high-temperature, and abrasive services.
Features an extended bonnet to create a vapor barrier, protecting the stem packing from freezing. Constructed from certified low-temperature materials (LCB/LCC, CF8/CF8M) to prevent brittle fracture at temperatures down to -196°C.
View SpecificationsDesigned for high-temperature or abrasive slurry services where soft seals would fail. Utilizes Stellite or other hard-facing alloys on the seat and disc to provide a durable, long-lasting seal in the most demanding environments.
View SpecificationsReliable and cost-effective solutions for handling corrosive chemicals, plant utilities, and general process fluids where absolute containment is key.
Provides the ultimate protection against aggressive chemicals. A thick, non-reactive liner completely isolates the valve body and stem from the corrosive media, offering a more cost-effective solution than exotic alloy valves.
View SpecificationsMore than a workhorse, it's an engineered asset. Thanks to a proprietary seat design, our resilient valves provide reliable, bi-directional bubble-tight shutoff—a level of performance typically reserved for high-spec valves.
View SpecificationsOur reliability is not just tested, it's built-in. By controlling the entire process from casting to final assembly, we eliminate the variables that lead to failure in the field.
Our roots are in casting. Led by a materials expert, we ensure every heat's chemical composition and treatment strictly conforms to ASTM/EN standards, guaranteeing predictable strength and corrosion resistance.
Our 11 CNC centers machine components to exact dimensional standards. This isn't just about a good fit; it's about ensuring perfect geometric alignment for reliable, repeatable sealing performance.
Our valve architectures are not theoretical. They have been refined and validated over two decades in the world's most demanding process plants, giving you unparalleled assurance of long-term reliability.
