Gas pressure regulator FRS Dungs
- These pressure regulators FRS are designed for gas burners and gas equipment.
- FRS has an adjustable setpoint spring which can be exchanged for different ranges.
- Input pressure up to 500 mbar (50 kPa).
- High flow rate
- The regulators are equipped with an inlet pressure compensation diaphragm and safety diaphragms.
- Internal pulse for regulator output pressure as standard, optional external pulse connection, optional on both sides.
- It does not contain any non-ferrous metals, suitable for gases up to maximum 0.1% din volum H2S, for gases of families 1, 2, 3 and other neutral gaseous media.
- Complies with EN 88 and DIN 3380.

The standard version is equipped with a blue spring.
Setting the response pressure
Factory setting standard spring p2: 10 - 30 mbar.
1) Unscrew protective cap A
2) Adjustment (+) - Setting spindle B "turn clockwise" = increasing response pressure (setpoint) OR
3) Adjustment (-) - Setting spindle B "turn counter-clockwise" = reducing response pressure (setpoint)
4) Check setpoint
5) Screw on protective cap A
6) Attach lead seal
