Why 100 PSI Matters

In microbiology autoclaves and fermenters, overpressure incidents above 100 PSI account for 14 % of lab safety alerts (OSHA, 2024). A properly rated pressure relief valve (PRV) prevents catastrophic vessel failure.

Key Functions

• Overpressure Protection: Opens within ±5 PSI of set point.
• Automatic Reseal: Closes once pressure drops 10 % below set value.
• Corrosion Resistance: 316L stainless extends service life to 5 years in humid environments.

Inspection Checklist

1. Verify set point annually with a calibrated gauge.
2. Check for seat deposits; debris can raise opening pressure by 20 %.
3. Document serial numbers for ISO 9001 traceability.

Conclusion

A 100 PSI PRV is a small investment that averts costly equipment damage and safeguards lab personnel.
