Reliability & Engineering Risk Analysis

Failure Mode & Root Cause
Contamination buildup
Cause: Particulate ingress from process environment or insufficient filtration, leading to clogged orifices, reduced airflow, and valve sticking.
Seal degradation
Cause: Exposure to incompatible media (oils, chemicals), excessive temperature, or cyclic fatigue causing leaks, loss of vacuum, or failure to actuate.
Maintenance Indicators
  • Audible hissing or whistling indicating air leaks at seals or fittings
  • Visible oil or debris accumulation on valve body or exhaust ports
Engineering Tips
  • Install and maintain high-quality coalescing filters upstream to protect internal components from particulates and aerosols
  • Implement regular preventive maintenance cycles to inspect and replace elastomer seals before end of service life, using manufacturer-recommended materials
