High Pressure Manifolds

MM400-2

Group Number: 2731

Manual changeover manifold with regulators MR60 or MR400 for high-flow applications for different gases with inlet pressure up to 300 bar. Manifolds contain inlet x-block with non-return valve and filter, purge valve and second inlet from site with the potential to install extension units. Purge valves can be used for pressure release when cylinder/ bundle hose is disconnected. There is also a high pressure shut-off valve, regulator with pressure relief valve and outlet ball valve mounted on the stainless steel panel.

Acetylene variant of MM400-2 is designed and produced in accordance with ISO 14 114. The inlet x-block with mounted purge valves, non-return valves and filters, enables safe operation with high pressure acetylene. There are used manual and also automatic quick acting shut-off valves upstream of the regulator. These devices are tested according to ISO 15 615. There is a flashback arrestor Simax 3 (EN 730-1, ISO 5175) fitted downstream of the regulator and also an outlet ball valve.

Outlet: G3/4“, DN20
