What is SIL (Safety Integrity Level)?

Safety Integrity Level (SIL) certification per IEC 61508 and IEC 61511 ensures valves meet quantified reliability requirements for safety instrumented systems (SIS). SIL-rated valves are critical components in Emergency Shutdown (ESD), blowdown, and depressurization systems in oil & gas and petrochemical facilities.

Valve Types

  • Emergency Shutdown (ESD) Ball Valve
  • ESD Gate Valve
  • ESD Butterfly Valve
  • Blowdown Valve
  • Depressurization Valve

Materials

  • ASTM A216 WCB / WCC
  • ASTM A351 CF8M (SS316)
  • ASTM A352 LCB / LCC
  • Duplex / Super Duplex
  • Inconel Overlay

Pressure Classes

  • Class 150 through Class 2500
  • API 6A rated (2000 to 20000 PSI)

End Connections

  • Flanged (RF, RTJ)
  • Butt Weld
  • Hub End (API 6A)

Frequently Asked Questions

What is the difference between SIL 2 and SIL 3?
SIL 2 requires a Probability of Failure on Demand (PFD) between 0.01 and 0.001 (risk reduction of 100 to 1000x). SIL 3 requires PFD between 0.001 and 0.0001 (risk reduction of 1000 to 10000x). SIL 3 is required for the most critical safety functions where failure could cause major hazards.
What certification body validates your SIL ratings?
Our SIL-rated valve assemblies are certified by Exida or TÜV Rheinland per IEC 61508. The certification covers the complete valve + actuator + solenoid assembly as a safety sub-system, with documented failure rates (λDU, λSD, λDD) and safe failure fraction (SFF).
Can you supply complete SIL-rated valve packages?
Yes. We supply complete SIL-rated packages including: valve body, pneumatic/hydraulic actuator, solenoid valve(s), limit switches, quick exhaust valve, and partial stroke test system. All components are selected and tested as an integrated safety sub-system.
Are SIL valves required for Saudi Aramco projects?
Yes. SAES-J-601 and SAES-J-605 mandate SIL-rated final elements for all Safety Instrumented Functions (SIF). ESD valves for Aramco projects typically require SIL 2 or SIL 3 with exida/TÜV certification and FMEDA (Failure Modes, Effects, and Diagnostic Analysis) reports.
