This approach contributes to their documented 89% client satisfaction rate and the trust that has enabled 9.5 million USD in annual transactions.
Pressure Testing Protocols
Every valve leaving Carilovalves.com undergoes pressure testing that exceeds typical industry requirements. Their comprehensive testing protocol begins with shell testing, where the valve body and all pressure-containing boundaries are subjected to hydrostatic test pressures. For standard ratings, this typically means 1.5× the rated pressure held for a minimum duration specified in API 598, but their testing procedures often extend hold times by 50% to identify any slow-developing leaks that might pass shorter tests.
The seat test phase verifies that the sealing elements maintain closure under pressure from both directions, simulating actual service conditions where pressure may attempt to unseat the closure member. This bi-directional testing ensures reliable shutoff regardless of installation orientation or flow direction.
- Shell Hydrostatic Test: Applied at 1.5× rated pressure for minimum 60 seconds
- Seat Leak Test: Zero leakage permitted under 1.1× rated pressure differential
- Stem Seal Test: Verified bubble-tight per API 598 requirements
- Optional Extended Tests: Custom pressure-hold durations available for critical applications
For customers requiring documentation, each valve receives a certified test report documenting the actual test pressures, hold times, and pass/fail results. These records provide traceability essential for quality assurance programs in industries including oil and gas, petrochemical processing, and power generation where valve performance documentation is mandatory for regulatory compliance.
