Bonomi ball valves gain SIL certification

09 July 2021

Bonomi (UK) Ltd ball valve supplier Valpres has obtained SIL certification for its Series 70, 71, 72, 73 and 76, 2-Way industrial ball valves.

Safety Integrity Level or ‘SIL’ in its abbreviated form, is a parameter relating to the functional safety integrity of industrial plants in the process industry. 

SIL awards a numeric value that represents an overall rating for the instrumented function. This rating tells you to what degree the instrumented function within a process automation system meets its requirements to mitigate risk, within a specified time frame. The applicable SIL is determined based on a number of quantitative factors in combination with qualitative factors such as development process and safety life cycle management.

The higher the numerical value of SIL achieved, the greater the risk reduction. Employing functional safety standards based on the IEC 61508 standard, the Valpres valves have achieved SIL 3 in the low demand mode category of industrial process applications.
