4. Surface Treatment→

Apply FBE/epoxy (min.250μm), passivate handles/flange faces to ASTM/ISO 12944-6.

5. Rubber Vulcanizing & Assembly→

Gate shoe is hot-cured with rubber, then precision assembled with stem, bonnet, gaskets.

6. ISO/ANSI Testing

Each valve 100% hydrostatic tested per ISO 5208/API 598 up to 1.5x PN max pressure.
