Important Note: The DN value embossed on the valve body indicates the NABIC 500 body size utilised in the manufacturing of this valve and does not correlate with the inlet or outlet size. For instance, a valve with 1" connections (DN25) is constructed using a DN20 NABIC 500 valve body, and thus, the DN20 will be marked on the side of the valve.
