The letters on the diagram correspond to the columns of the dimension table below.
"Open" means a ring in the flow (passage is open); "Muffled" means a disk (flow is blocked).
Loosen the bolts, turn the "glasses" around the bridge, tighten — without removing the flanges.
It is mounted between flanges with gaskets as an inter-flange element.
The diameters of the ring and disc, the thickness and parameters of the bridge are according to ATK 26-18-5-93, depending on the DN, Pn and the connecting dimensions of the counter flanges. We will match it to your flange assembly.
These are two elements — a ring and a blind disc connected by a jumper. By turning between the flanges, either a ring is installed (the passage is open) or a disk (the section is plugged).
Allows you to change the "open/closed" position without completely disassembling — just loosen the bolts and turn.
