DIVERSE INDUSTRIES
CTGV Valve Solutions Across Critical Industries
From LNG to chemical systems, Tiangong valves perform under pressure, temperature, and corrosion challenges.
Oil & Gas
CTGV valves are designed for high-pressure, corrosive oil and gas environments. With cryogenic sealing at -196°C, our valves ensure zero leakage in LNG storage and long-distance pipelines. Constructed from corrosion-resistant materials, they reduce maintenance costs in sulfur-rich oilfields, supporting efficient extraction.
Chemical
In complex chemical processes, CTGV provides fully fluorine-lined valves that resist strong acids and alkalis perfect for PVC, PTA, and fine chemical production. Our products meet several standards, preventing toxic backflow and ensuring safety in reactor systems and pipelines, helping reduce leak risks in complex processes.
Power Generation
Designed to endure up to 600°C, CTGV valves are crucial for power generation systems. From main steam systems to feedwater control, our valves optimize energy efficiency, reduce thermal losses, and support long intervals between maintenance cycles. They integrate seamlessly with DCS systems for smart, efficient plant operations.
Steel
In the steel industry, CTGV offers valves that resist high-temperature abrasion and dust in blast furnace gas systems. With large-diameter designs and bi-directional sealing, our valves manage up to 800°C and protect against wear, offering zero leakage and reducing the need for costly replacements.
Metallurgy
CTGV valves, resistant to high temperatures and thermal shocks, are ideal for non-ferrous metal refining and slag control. Coated for oxidation resistance, they protect molten metal pipelines and manage slag-water pressure, enhancing equipment lifespan in copper and aluminum production.
Water Supply & Drainage
CTGV produces valves for municipal water, wastewater, and sponge city systems. With eco-friendly, low-leakage designs, they ensure precise flow regulation, quick installation, and reduced clogging risks, all while meeting international standards like GB/T 12238 for sustainable infrastructure.

CASE STUDY
Global Success with CTGV Valves
Solving industrial challenges with precision-engineered valve solutions.
Triple Offset Valves for Northern District Heating Pipelines
CTGV supplied triple offset butterfly valves to handle –30°C to 120°C temperature swings. The system achieved three heating seasons of zero leakage, boosting thermal efficiency by 8% and cutting maintenance costs by 65%.
Cryogenic Valves for LNG Terminal Pipeline Safety
For –162°C LNG lines, CTGV delivered nickel-steel triple offset valves with PTFE-metal seals. Achieved four years of leak-free performance, passed DNV STF 670, and met emergency shutoff standards under 0.5 seconds.
Standardized Valve Supply for Pipeline Network
In a 70-km water pipeline project in the Middle East, CTGV supplied WRAS-coated valves. 3D-assisted installation enabled seamless fit, extending maintenance cycles by 40%.
