4.2 PRESSURE REGULATORS PRODUCT LINE 500

A maximum of six (in some cases four) inlet 

and outlet bores with NPT 1/4” female thread 

allow a wide range of options for connecting and 

adapting the pressure regulator. Please follow 

in the case of device change the hints in the 

chapters 6. and 7.

4.3 CYLINDER PRESSURE 

REGULATORS

The FMD 500/502 is designed to reduce high 

cylinder pressure to the lower supply pressure 

range. According to DIN 477, the cylinder 

connections have particular connection threads.

FMD 500/502-14/16/18

Single stage (double stage) cylinder pressure 

regulators  with  outlet  tube  fitting  (-14)  or  with 

divers additional device like shut-off valve (-16) 

or metering valve (-18).

FMD 500/502-21 

The FMD 500/502-21 model allows external purging using a purge valve (inlet) and the process valve 

(outlet). By this means the pressure regulator is specially used with flammable, reactive or corrosive gases.
