Tantaline Treated Valve Body


 Cost-Effective Tantalum Solution

► Outperforms Nickel Alloys, Titanium & Zirconium

► Quick Lead Times: 3-4 Weeks

► FDA Approved Material

► 20+ Years' Proven Experience

Tantaline is the world’s leading producer of tantalum surface alloys for valves, fittings, heat exchangers, lab reactorsinstrumentation, and custom products in hot concentrated acid environments like hydrochloric acid and sulfuric acid. Through its innovative tantalum vapor technology, Tantaline delivers the most corrosion resistant material commercially available today for the chemical processing, oil and gas, pharmaceuticals, next generation energy and mining industries.

Tantaline has been helping out customers for more than 20 years offering them higher corrosion performance than titanium, zirconium and Hastelloy* (nickel alloy). In most hot concentrated acid environments, Tantaline offers longer service life than Hastelloy* C276.

The secret to the Tantaline solution is its longer service life, shorter lead times, and cost-effective pricing versus the traditional Hastelloy C276, titanium,  and zirconium options. For these reasons, Tantaline has become the market leading choice for severe corrosion applications, outperforming traditional specialty metals, plastics, and fluoropolymer (e.g. PFA & PTFE). The Tantaline performance is validated in a number of case studies

* Hastelloy is a trademark by Haynes International.



Valves from leading OEMs, including AZ-Armaturen, Flowserve, UNI-Valve and Swagelok, are available from Tantaline. Valve styles available include: Ball, plug, check, butterfly safety relief, and specialty valves.
