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 pressure up to 50 mbar (5 kPa) for zero pressure applications Input pressure up to 200 mbar (20 kPa) for proportional pressure applications
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 set point spring and defined counterspring. Internal tap of regulator output pressure, external pulse and blower pressure connections prepared. Suitable for controlling regulator output pressure via a pneumatic command variable.
