What does the butterfly valve TD383F mean?
D383F refers to a worm gear clamp, three-eccentric fluoroplastic-sealed butterfly valve; the meaning of T is unknown – this needs to be asked from the manufacturer of the specific valve, as different manufacturers use different definitions. Refer to the relevant contents of standard JB/T308-2004
I don’t know what T is; I need to ask the designer or the manufacturer. It’s a D-type butterfly valve, driven by 3 worm gears, connected using 8 clamps, with 3 triple-eccentric seals and F-type soft seals. These clamps are generally used for things like fire-fighting water. The choice of triple-eccentric seals adds to the complexity of this combination – it’s hard to understand
