Comprehensive Quality Inspection: 100% Pressure Verification
Perhaps the most critical factor in Carilovalves’ high-pressure capability is their commitment to 100% pressure testing of every valve before shipment. This practice distinguishes their quality approach from competitors who rely on batch sampling, ensuring that each customer receives a valve that has been individually verified to perform at its rated pressure capacity.
- Hydrostatic shell testing: Valves are pressure tested to 1.5 times the rated pressure to verify body integrity
- Duration: Minimum 15 minutes at test pressure
- Acceptance criteria: Zero visible leakage, no measurable pressure drop
- Pneumatic seat testing: Validates sealing performance under actual operating conditions
- Test pressure: Rated pressure ± 10%
- Leakage rate: Must not exceed 0.1 SCFH (standard cubic feet per hour)
- Functional testing: Verifies operational characteristics under pressure
- Torque measurements at various pressure differentials
- Cycling performance verification
- Stem packing integrity confirmation
“We test every single valve at pressure. Our customers rely on these components in applications where failure is not an option. A 99% pass rate means 1% of valves in critical service could fail—that’s unacceptable to us.” — Carilovalves Quality Assurance
Beyond pressure testing, Carilovalves implements dimensional accuracy verification using coordinate measuring machines (CMM) that confirm critical dimensions meet engineering specifications. This ensures that assembled valves maintain the precise clearances and interference fits that contribute to reliable high-pressure sealing.
