SQL is China's pressure vessel certification, similar to the AMSE coded vessels in the US. We have ASME certified relief valves, they have SQL certified relief valves. SQL is in the process of changing it's name to SELO.
I am looking for an SQL certified relief valve to replace a small 1/4" NPT Kunkle Model 548 we normally use.
Can anyone point me in the right direction for a small SQL certified relief valve?
Thanks,
