1.2 Description of the Series FE51/52/53-SP and FE121-SP
Cylinder pressure regulators of the FE51/52/53-SP and FE121-SP Series are single-stage cylinder pressure
regulators with pressure gauges for measurement of the inlet and outlet pressure. The main task of the
cylinder pressure regulator is to reduce the inlet pressure to the outlet pressure required for the specific
application.
The letters "SP" denote cylinder pressure regulators equipped with a purge device
The purge device is used, for example, in applications where penetration of atmospheric gas into the gas-
wetted area of the downstream pipe system up to the connected equipment is not desirable, requiring
purging of the atmosphere before the pipe system is connected.
The purge device is also used to flush toxic or corrosive process gas from the pressure regulator before it is
removed from the gas cylinder, e.g. when changing the cylinder, preventing such gases in unpurged fittings
reaching the surrounding atmosphere.
