• Sand Blasting Surface Treatment SA2.5
1. The valve body is meticulously sandblasted inside and out to ensure a pristine and uniform surface.
2. Post-sandblasting, the surface is exquisitely fine, ensuring robust paint adhesion and extended durability.
3. If the oxygen content in the medium exceeds 23.5%, only external sandblasting is necessary, making internal sandblasting redundant.•
