Regulator S4

Fixed setting medium pressure

Type “B” regulator is usually installed upstream of the meter and it ensures the supply to the equipment of the industrial buildings, to the boiler rooms and commercial facilities which make use of natural gas or propane ( 150 to 300 mbar ) starting from a medium pressure distribution system ( 0.8 to 5 bar ).
It can be installed in protected systems, such as vertical services ducts or in cabinets; in this case we are referring to OVERHEAD connections, or it can be installed in aggressive environments, the so-called UNDERGROUND connections, which require special options.
