Description The DUNGS FRS 7../6 pressure regulator is a spring-loaded pressure regulator with adjustable setpoint spring. 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 DUNGS FRS 7../6 pressure regulator is recommended for industrial and commercial heating applications and is suitable for natural gas, propane, butane, air and other inert gases.
