6” ANSI – 150#, 300#, 600# or 900# 304, 316 - Duplex Stainless Flanges
Turndown
1200:1 Turndown is typical of normal operations. Turndown ratio can vary significantly depending on installation and process conditions. Actual turndown may be much greater than 1200:1 in some conditions such as water draw, or much less in high pressure, dry product applications such as NGL service.
