Description The DUNGS FRS 7../6 line pressure regulators, are a balancing type, spring-loaded regulator with an adjustable setpoint. They feature an internal sensor for regulating output pressure. - Input pressures up to 10 PSI (CSA to 5 PSI)

- High flow rate

- Sturdy, precise and sensitive regulation of regulator output pressure

- Lock-up Type Regulator

- Vent limiter; approved as a vent-less regulator by some authorities having jurisdiction. (Review applicable codes for vent line requirements)

Application The FRS series line pressure regulators are recommended for any application requiring a line regulator to drop inlet pressures to a lower pressure suitable for an appliance or equipment. Suitable for natural gas, propane, butane, air and other inert gases.
