FRNG Pressure Regulator DN 40 DN 50

The DUNGS pressure regulator, type FRNG, has an adjustable setpoint spring and defined counterspring. The pressure regulator complies with EN 88-1 and DIN 3380:

• Input pressures up to 200 mbar (20 kPa) for zero pressure applications
• Input pressures up to 200 mbar (20 kPa) for proportional pressure applications
• Bypass prepared, 3/8 to  2
• 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

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 met-als, suitable for gases of up to max. 0.1 vol.% H2S, dry.
