23/03/2010 - AMPO-POYAM VALVES announces that their BALL VALVES have received SIL 3 certification per the IEC 61508 international safety standard. Up to this point, the prior use methodology has been required to demonstrate the valves are "proven in use" for safety applications. In addition to this SIL 3 is defined as a relative level of risk-reduction provided by a safety function, or to specify a target level of risk reduction. In simple terms, SIL is a measurement of performance required for a Safety Instrumented Function (SIF).

Having these valves certified for up to SIL 3 safety instrumented functions provide process manufacturers great flexibility in the selection of final elements for their IEC 61511 safety compliance efforts.
