Ball valve, CL800, A351 CF3M, TRIM: 316/RTFE, RB, 3PSC, FLB, NBE, 8A; medium: TEAL, SWAGELOK (FIRE SERIES “A60”), MFRS. Can the connection method of the valve be determined from these specifications (flange connection, welding, threaded connection)?
It should have a short tube added, welded on, I guess
Add a short section. It does not indicate whether welding is required. But it is a floating ball valve, lined with RTFE; it is not welded.
800LB: standards available only for socket welding, butt welding, and threading
What size are these 800LB ball valves? The connection method cannot be determined from the above.
