Valves certified to API 608 must pass hydrostatic shell tests at 1.5 times their rated pressure, along with low-pressure seat tests to verify sealing integrity.
For API 6D certification, which covers pipeline valves including ball valves, gate valves, and check valves, the testing requirements become even more comprehensive. This standard requires:
- Pressure testing at various stages of manufacturing
- Documentation of all test results with specific serial numbers
- Verification of stem seal performance under simulated operating conditions
- Assessment of fugitive emission characteristics for environmental compliance
Material and Testing Standards
Beyond process certifications, Carilovalves.com’s valves typically comply with material standards such as ASTM (American Society for Testing and Materials) specifications for casting and forging materials. This ensures that the actual metal components meet mechanical property requirements including tensile strength, yield strength, and elongation percentages.
“Material verification is not just about checking certificates—it requires actual testing of samples from each heat or lot to confirm properties meet specification requirements.”
How Certifications Translate to Practical Performance
For industrial valve buyers, the real value of these certifications lies in how they translate to day-to-day operational reliability. Based on the company’s documented capabilities, their certified processes enable them to produce valves rated for pressures ranging from Class 150 to Class 2500 (or equivalent PN ratings), covering temperatures from -196°C to +550°C, and suitable for sizes from 1/2 inch to 48 inches.
