Outlet Pressure Range: 7″ to 14″ wc
The NMT® N5 OPD (Overpressure Protection Device) Series gas regulator is an ANSI Z21.80 certified self-operating OPD two-stage regulator with vent limiting for use in residential, commercial, and industrial applications. The OPD function allows for installation in applications where pressures must be limited to 2psig per ANSI Z21.80. The standard vent limiting feature allows for indoor use without the need to pipe external vent lines while still maintaining OPD protection.
Features
- ANSI Z21.80 certified
- Vent limiter STANDARD (No need to install vent pipe!)
- Multi-position installation
- Extended corrosion resistance
- Up to 10 psig operating pressure
Specifications
- Maximum inlet pressure: 10 psig
- Maximum Emergency Inlet Exposure Pressure: 85 psig (inlet side only)
- Ambient Temperature Range: -40°F to +212°F
- Gas Type: Natural gas, LPG, air, other non-corrosive gas
- Options: Vent cap, vent elbow

NGRB Series
Read moreNGRB
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
