Switch valve SIL certification
Thread Content
My company wants to purchase pneumatic switch valves with SIL certification; I’ve contacted several suppliers, and in each case the certification is issued separately – one certification for the valve body, one for the cylinder, one for the solenoid valve, and one for the limit switch； I would like to ask if this meets the requirements? ? Are there any types that offer integrated certification for (valve + cylinder) or (valve + cylinder + solenoid valve + position switch)? Is it available in China? Please recommend some

SIL certificates are issued as individual certifications. The MARS ball valves imported by our company come with certifications such as SIL3, fire protection, explosion protection, API607, TA-LUFT, and CE; all of these are issued by internationally renowned certification bodies, so there is no risk of such certifications not being recognized

Unless their company manufactures everything, including positioners, control valves, cables, power supplies, feedback switches, and so on! Moreover, it seems that the authentication methods for each part are different; how can overall authentication be carried out? So, there is no overall certification.
