Medium pressure regulator FRM Dungs
- These pressure regulators FRM are designed for industrial gas burners and gas heating appliances. They can be used for installation in the municipal and commercial gas supply.
- Spring-loaded, pressure compensating regulator with adjustable setpoint springs for regulation of the regulator outlet pressure.
- External impulse of the regulator outlet pressure.
- Type IS - internal strenght range.
- Inlet pressures up to 10 bar (1000 kPa).
- Ambient temperature -20÷60o.
- Models with integrated safety shut-off valve SSV (SAV) in compliance with EN14382, class A, with a response time of under 2 seconds, a lower adjustment range Wdu between 10÷2500 mbar and an upper adjustment range Wdo between 40÷4000 mbar.
- Failure mode (diaphragm rupture): fail-open.
- Accuracy class up to AC 5.
- High flow rate. Stable, accurate and sensitive regulation of the regulator outlet pressure.
- Materials: main body housing - cast iron GGG 50, diaphragm housing - steel, diaphragms - NBR.
- Suitable for gases of gas families 1, 2, 3 and other neutral gases.
