NGRB Series
NGRB
Pipe Size: 2″ and 3″ FL
Outlet Pressure Range: 7″ to 21.4 psig
The NMT® NGRB Series regulators are single stage, self-operated regulators for heavy duty work under high, medium and low-pressure applications, for all types of non-corrosive gases. The NGRB Series regulator has a built-in partial relief valve (token relief), which allows occasional rises in the outlet pressure above the relief pressure to be released gradually into the atmosphere without triggering an overpressure shut-off valve or high limit switch due to occurrences such as sudden variations in flow or variations in temperature causing an increase in downstream pressure.
NOTE: The NGRB regulator requires a downstream sensing line that senses the downstream pressure to operate. This sensing line must be installed within the piping system and connected to the regulator at its appropriate connection.
Features
- Internal token relief
- Corrosion-resistant exterior
- High capacity at low inlet pressures
- Internal balanced valve allowing low lock up with high inlet pressures
- Field-interchangeable springs
- Designed for easy maintenance
Specifications
- Gas types: Natural gas, LPG, other non corrosive dry gases
- Maximum inlet pressure: 145 psig
- Maximum emergency inlet pressure: 145 psig
- Operating temperature: -4°F to +140°F
