This control standard refers to clauses of prEN 13611:2005 or adapting it by stating “ Addition” , “ Modificatio
16、n” or “ Replacement” in the corresponding clause. It introduces requirements for balanced valves and a method for the assessment of other means for closing and/or sealing in automatic shut-off valves. SIL classification according to EN 61508 cannot be claimed based upon compliance with this standard
17、. Valves with SIL classification do not meet automatically the requirements of this standard.
