Karl Dungs FRS Gas Pressure Regulators

Karl Dungs FRS Gas Pressure Regulators

  • Max. Operating pressure:
    • 7 PSI (500 mbar) CE
    • 5 PSI (350 mbar) CSA
  • Connection: NPT, DN  or Rp
  • Input pressure range: 2″ W.C. to 200″ W.C. (5 mbar to 500 mbar)
  • Output pressure range: 1″ W.C. to 80″ W.C. (2.5 mbar to 200 mbar); adjustable with different springs

Description

The DUNGS FRS 7../6 Series NPT Threaded (CE Approved), FRS 5… Flanged (CSA Certified) and FRS 5.. Rp Threaded (CE Approved) pressure regulators are spring-loaded pressure regulators with adjustable setpoint spring. Internal sensor for regulating output pressure.  Flanges sold separately.

  • Input pressures up to 7 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 gas pressure regulators are recommended for industrial and commercial applications, and they are designed for high efficiency appliances, high-turn down appliances, appliances using direct spark ignition or hot surface ignition, and other applications requiring a high performance regulator. The FRS is suitable for dry natural gas, propane, butane, air and inert gases.

Ask us for engineering or product support to size your regulator.
