Yes. We ship DAP to Phoenix Sky Harbor for distributor warehouse delivery, or with inland trucking to mine sites in the Morenci, Miami, and Bagdad districts.

What is the most common Alloy 20 valve for Arizona raffinate loops?

Dual-plate wafer check valves per API 594 in full CN7M construction with spring-assisted non-slam closure — typically NPS 2" to 6" Class 150.

Can we order a single valve for field trial before a plant-wide upgrade?

Yes. Qty 1 orders with full EN 10204 3.1 MTC and API 598 test reports are standard for engineering verification.
