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 H2S. A “dry” gas has a dew point lower than +15 °F and its relative humidity is less than 60 %.
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.
Features:
- Input pressures up to 10 PSI (See specifications for more details) and NPT ½” 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.
- Factory installed vent limiter. Review applicable codes for vent line requirements.
