The FRS 7../6 Threaded & FRS 5… Flanged balancing type pressure regulators are spring-loaded pressure regulators with an adjustable setpoint. Both feature an internal sensor for regulating output pressure.
- Input pressures up to 10 PSI (See specifications for more details) and NPT _” to NPT 3” thread connections (FRS 7../6)
- Input pressures up to 7 PSI and DN 40 to DN 150 flanged connections (FRS 5… Flanged)
- Heavy duty diaphragm construction for durability and strength.
- Steady, precise and instantaneous regulation of the outlet pressure.
- Lock-up type regulator (see page 2 and 3 for details).
- Factory installed vent limiter. Review applicable codes for vent line requirements.
- Max. Operating pressure: 7 PSI / 5 PSI
- Nominal diameter: NPT 1/2 - NPT3, DN 40 - DN 150
- Approvals: EN 88
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. The FRS does not contain any non-ferrous metals and is suitable for gases containing no more than 0.1 % by volume, dry H2 S. A “dry” gas has a dew point lower than +15 ¡F and its relative humidity is less than 60 %.
