SIL 3 Certification for Oliver Twinsafe ’ s Single Isolate and Double Block & Bleed Valves
Oliver Twinsafe Trunnion Mounted valves and Floating Ball Valves have successfully been SIL certified at level 3 . This new and important milestone provides operators with safety assurances at the highest level and has resulted from many months of engineering design , QA reviews , and audits .
A SIL ( Safety Integrity Level ) is a measure of safety system performance , in terms of probability of failure on demand ( PFD ). The higher the SIL level , the higher the associated safety level , and the lower probability that a system will fail to perform properly . SIL 3 is the highest rating that can be given to a valve .
High Integrity Pressure Protection Systems ( HIPPS ) and remotely located well-head manifolds are normally associated with SIL certification . Operators are to gain additional safety assurances from installing our ball valves , in that , when the valve is required to perform its fail-safe function , the probability of it not performing is extremely low .
SIL 3 certification has been awarded by Exida , a third-party safety assessment organisation . The certification covers our range of Single Isolate valves , and Double Block and Bleed valves comprising two separate isolates within the assembly . Bore sizes for Trunnion Mounted valves range from 1 ” – 16 ” and 1 ” – 3 ” on Floating Ball valves .
