Group Number: 2731

High pressure manifold based on Manyflow unit for middle and low flow rates.

It can be used for oxygen and inert gases. It is designed for cylinder or cylinder bundles service. There are non-return valves at the Manyflow inlets, separated isolating valves and one central inlet shut-off valve. UC 500 regulator contains high pressure and low pressure gauges and pressure relief valve. There is outlet low pressure ball valve downstream regulator. Gas wetted components are made of brass. All components are fixed to the stabilizing stainless steel wall bracket.

MB 70 for acetylene is design and produced in accordance with ISO 14 114. Manyflow is tested and approved in accordance with ISO 15 615 as well as high pressure automatic quick acting shut-off valve and pressure regulator UC 500. There are also pressure relief valve, high pressure and low pressure gauges. Low pressure flashback arrestor GVA 90 (EN 730-1, ISO 5175) consists of filter, flame arrestor, thermal arrestor and non-return valve. Outlet ball valve is mounted downstream FBA.
