Information

In enterprises where the central system is installed and available, the pressure of the gas coming from the source (fixed or mobile, tube pallets, cylinders or special containers) is reduced to the pressure level required by the central system with the high-pressure manifold with a regulator.

Features:

• It offers high compressed gas (O, D, N, CO2) up to 600 Nm³ /h and up to 230 bar inlet pressure.
• A maximum inlet pressure of 230 bar is reduced to outlet levels of 10 bar, 20 bar, or 40 bar.
• Equipped with 2 cylinder connections with valves, suitable for use with individual cylinders or cylinder bundles.
• Extension connections on both inlet sides allow additional cylinders or bundles to be connected to the system by purchasing extra cylinder valve connections.
• While one side of the system is operating, the other side remains on standby. When the cylinder or bundle is emptied, the gas flow automatically switches to the other side, ensuring uninterrupted operation.
• The central lever can be turned upward or downward to select the active gas line.
• All components of the system are mounted on a high-strength stainless steel sheet.
• Thanks to the vent valves located on the inlet sides, the gas inside the system can be safely discharged before cylinder replacement or maintenance.
• In oxygen systems, a flashback arrestor is installed before the ball valve on the outlet line.
• Check valves located at both cylinder connection valves prevent gas backflow, thereby enhancing system safety.
• Thanks to its compact design, it occupies minimal space while its cost-effective structure reduces investment expenses.
• The safety relief devices located in the pressure regulators ensure safe venting of excess pressure in case of malfunction.
