The manifold is designed for supplying oxygen (and other products of air separation (cryptoproducts (Az, Ar, O2, Kr, Xe…), welding protective mixtures based on Ar and CO2, helium He and compressed air from cylinders through a common collector to the consumer. TECHNICAL SPECIFICATIONS  Item  Value Number of leads 10 Thread connection of cylinder G3/4-B The distance between the axes of the valves, mm 280 Internal diameter of the collector, mm 25 Maximum working pressure at the entrance to the manifold, bar (MPa) 200 (20) Test pressure, bar (MPa) 300 (30) Overall dimensions, no more, mm 2780x290x310 Weight no more, kg 24 STRUCTURE AND PRINCIPLE OF OPERATION The manifold consists of a collector, bypass valves, cylinder inlets, a fitting for installing a pressure gauge with a plug. The collector is a tubular body with G3/4 fittings on the ends, 10 fittings with union nuts M22x1.5 – for installation of bypass valves (VK-20 R ramp). A fitting for a pressure gauge with a plug is installed on the collector. Bypass valves are installed in the fittings on the collector, to which balloon inlets are connected. The cylinders are connected to the manifold with G3/4 union nuts on the cylinder leads.
