Dungs Zero Pressure Regulator FRNG 5050

Technical description

The DUNGS pressure regulator, type FRNG, has an adjustable setpoint spring and defined counterspring. The pressure regulator complies with EN 88 and DIN 3380:

• 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.
