Input pressures up to 50 mbar (5 kPa) for zero pressure applications
Input pressures up to 200 mbar (20 kPa) for proportional pressure applications
Bypass prepared
Sturdy, precise and sensitive regulation of regulator output pressure
Inlet pressure compensation diaphragms
Safety diaphragms
Internal pulse for regulator output pressure as standard, external pulse connection prepared
Connection for blower pressure as standard
Nominal diameter DN50, flange connection as per DIN EN 1092-1
Application
The DUNGS pressure regulator, type FRNG, is suitable for gases of families 1,2,3 and other neutral gaseous media. Does not contain any non-ferrous metals, suitable for gases of up to max. 0.1 vol.% H2S, dry.
FRNG
Spring-loaded pressure regulator with adjustable setpoint spring and defined counter spring. Internal tap of regulator output pressure, external pulse and blower pressure connections prepared. Suitable for controlling regulator output pressure via a pneumatic command variable.
