Titanium Ball Valve Suppliers & Exporter Serving The Bangkok Market

While nickel alloys like Hastelloy C-276 and Super Duplex stainless steels resist many acids, titanium Grade 2 and Grade 7 exhibit essentially zero corrosion rates in chloride-rich environments, seawater cooling, and wet chlorine gas due to their rapidly reforming TiO2 passive film. Furthermore, titanium has a density of 4.51 g/cm³—roughly 45% lighter than Hastelloy (8.89 g/cm³)—minimizing structural load-bearing constraints on offshore skids and suspended pipe racks in industrial complexes.

Jovzi supplies full and reduced bore titanium ball valves ranging from 1/2" up to 16" (DN15 to DN400). End connections adhere strictly to ASME B16.5 Class 150, Class 300, and Class 600 flanged dimensions, as well as JIS 10K/20K standards frequently utilized by Japanese-invested industrial plants across Chonburi and Rayong. Butt-weld, socket-weld, and NPT threaded bodies are manufactured per customer drawings.

Yes. Jovzi routinely provides China-ASEAN Free Trade Agreement Certificates of Origin (Form E) alongside complete commercial invoices, packing lists, and bill of lading (B/L) files. Under Form E guidelines, qualified Thai importers can secure significant tariff reductions or zero-duty exemptions upon customs clearance at Bangkok Port (PAT) or Laem Chabang Port.

Every valve undergoes rigorous pressure testing in strict accordance with API 598 or ISO 5208 standards, including high-pressure hydrostatic shell tests, hydrostatic seat tests, and low-pressure pneumatic air seat tests to confirm Class VI zero bubble leakage. Non-destructive examination (NDE) methods—such as 100% Positive Material Identification (PMI) by XRF, liquid penetrant testing (PT), and ultrasonic testing (UT) on raw forgings—are documented and included in the shipping dossier.

For operational temperatures up to 180°C, virgin PTFE and reinforced PTFE (RPTFE) provide reliable chemical inertness and low actuation torque. For abrasive slurries or high-temperature lines up to 260°C in chemical processes, PEEK, Devlon, or metal-to-metal seats with specialized thermal-sprayed tungsten carbide (WC) or chromium carbide coatings are integrated to prevent ball-seat galling while maintaining absolute shut-off integrity.
