The connection dimensions (D, K, d, n) match the counter flange according to 33259. Values for Ру16 (example); Ру6/10/25/40 and more — on request. b is the thickness.
The flanged (blind flange) is installed instead of the counter flange and completely disconnects the section with a bolted connection. The rotary ("glasses") switches the section between "open" and "turned off" without dismantling.
Yes — D, K, d, n correspond to the counter flange according to ГОСТ 33259 for the same Dn/Pn.
