What pressure classes are available for Alloy 20 valves shipped to Louisiana?

We manufacture Alloy 20 valves in Class 150, 300, and 600 per ASME B16.34. Flanged ends per ASME B16.5 with RF or RTJ facing. Wafer check valves per API 594 with face-to-face per Table B.

Are Alloy 20 valves from India subject to Section 301 tariffs in the USA?

Valves manufactured in India are not subject to the 25% Section 301 tariffs that apply to Chinese-origin valves under HTSUS 8481. This makes Indian Alloy 20 valves significantly more cost-effective for US chemical plant procurement.

Can you supply a single valve for engineering verification before a bulk order?

Yes. We accept quantity-one orders for engineering trials and material verification, including dual-plate wafer check valves in Alloy 20 with complete MTC and hydrostatic test documentation.
