Safety valves play a critical role in protecting pressure equipment, pipelines, and industrial systems from overpressure. To ensure safe and compliant operation, these valves must be regularly tested, calibrated, and recertified according to international standards.
At Spektr Group, we perform full-cycle recertification of safety valves for a wide range of industrial applications, including Oil & Gas, Petrochemical, Manufacturing, Utilities, and Offshore operations.
How the Recertification Process Works:
1. Incoming Inspection
Each valve undergoes a detailed visual and mechanical inspection.
We check:
• Body condition
• Seat condition
• Spring integrity
• Set pressure adjustments
• Leak points
2. Functional & Set-Pressure Testing
• Valves are placed on calibrated test benches to verify:
• Opening (set) pressure
• Reseating pressure
• Tightness and leak rate
• All tests follow international standards such as API, ASME, and EN.
3. Repair and Parts Replacement (If Needed)
• If the valve fails the test, we perform:
• Lapping and cleaning
• Spring and seal replacement
• Seat repair
• Stem and guide service
• Full internal refurbishment
• Only certified parts and approved materials are used.
4. Calibration & Final Testing
• Once repaired, the valve is retested to ensure:
• Accurate opening pressure
• Stable reseating
• Zero leakage within the allowable limits
• Full compliance with standard requirements
• Each result is recorded with precise measurements.
5. Certification & Documentation
Upon successful testing, the valve receives a Recertification Certificate, including:
• Test bench calibration details
• Set pressure results
• Repair work summary
• Compliance references
• Technician signatures
• This provides complete traceability and ensures regulatory compliance.
Why Safety Valve Recertification Matters
✔ Prevents equipment failure and shutdown
✔ Protects personnel and operations
✔ Ensures compliance with regulations
✔ Extends valve lifespan
✔ Reduces operational risks and costs
At Spektr Group, we combine technical expertise, advanced test equipment, and strict quality standards to deliver reliable recertification services for safety-critical environments.
