Central pressure regulators or main pressure regulators, describes pressure reduction valves that reduce the high pressure from main containers (compressor tanks, cylinder batteries or liquid gas tanks) to an intermediate pressure.
The central pressure regulator ZDA 25 reduces a maximum inlet pressure from 25 bar down to 1.5 bar. Suitable for connection to acetylene batteries and 2x3 bundles.
The cylinder pressure regulator HD 30 reduces the bottle pressure from under pressure dissolved gases as well as liquid gases from max. 300 bar down to 30 bar max.
