Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. has evolved into a powerhouse of international trade and engineering manufacturing. Our expertise spans a comprehensive range of carbon steel, alloy steel, and stainless steel solutions, conforming to ASTM, ASME, EN, and JIS standards.
Beyond traditional manufacturing, under the leadership of Chairman Mr. Ming SUN, we have pivoted towards clean energy technology and advanced flow control systems. Our commitment to environmental protection and technological innovation has earned us the National High-tech Enterprise certification and recognition at global stages like COP28 Dubai.
Unlike standard butterfly valves, the TOBV incorporates three separate offsets: the shaft axis, the disc axis, and the seat cone axis. This geometry ensures the disc only contacts the seat at the final point of closure, eliminating friction and extending service life.
Our Triple Butterfly Valves utilize a metal-to-metal seal with a laminated seal ring (stainless steel + graphite). This configuration achieves "Bubble Tight" shut-off (API 598), making it ideal for high-pressure and high-temperature environments.
Tested to API 607 standards, our valves maintain integrity even in extreme fire conditions. The torque-seated nature of the valve allows it to tighten under pressure, providing a bi-directional seal that remains reliable over thousands of cycles.
Triple Butterfly Valves are critical in upstream, midstream, and downstream operations. They handle severe service applications, including cryogenic LNG storage and high-heat refining processes, where gate or ball valves might be too bulky or costly.
From steam isolation to cooling water systems, Shaanxi Kerlimar provides valves that can withstand the thermal cycling typical of modern power plants, including those utilizing renewable wind power technology developed in our own R&D centers.
For large-scale desalination and municipal water distribution, our corrosion-resistant coatings and stainless steel materials ensure long-term performance without contamination.
Leveraging China's robust steel supply chain, we offer premium Triple Offset Valves at a 30-40% lower TCO (Total Cost of Ownership) compared to European or American counterparts without compromising on alloy quality.
With 40+ patents and a focus on "New Productivity," we integrate AI-driven design optimizations to ensure flow coefficients (Cv) are maximized, reducing pumping energy costs for our clients.
Our products undergo rigorous third-party inspections (SGS, TUV, BV) and meet international standards including ASME B16.34 and API 609, ensuring seamless integration into global projects.
The global valve market is shifting towards Digitalization and Sustainability. As we move towards the "Double Carbon" goals, valves are no longer just mechanical components; they are data nodes. At Shaanxi Kerlimar, we are exploring:
A "famous" valve is defined by its reliability in critical failures. High-performance triple offset valves are renowned for their ability to provide tight shut-off in high-pressure steam and hydrocarbon services where standard butterfly valves fail.
Yes. Our factory specializes in extended bonnet designs for cryogenic applications down to -196°C, ensuring the packing gland remains at an ambient temperature to prevent leakage.
Typical lead times range from 6 to 12 weeks depending on material availability (e.g., special alloys). Our integrated supply chain in Shaanxi allows for faster turnaround than most global competitors.
Our Triple Offset Butterfly Valves are designed for bi-directional shut-off, meeting the highest leakage class requirements in both directions, which is essential for pump isolation and storage tank applications.
| Valve Type | Temperature Range | Sealing Class | Primary Application |
|---|---|---|---|
| Triple Offset Butterfly | -196°C to +600°C | Zero Leakage (API 598) | High-Pressure Steam, LNG, Chemicals |
| Concentric Butterfly | -10°C to +120°C | Resilient Seated | Water, HVAC, Low Pressure |
| Double Offset (High Perf) | -40°C to +250°C | Class VI | Corrosive Media, Utilities |
