Series NR Regulator
Brand: Generant IncDesigned specifically for Large Vehicle NG Fueling Systems, the Series NR features our unique pre-formed Phosphorous Bronze Dual Diaphragm Stack providing increased sensitivity to changes in fuel demand over conventional flat sheet metal diaphragm designs.
The metal diaphragms also provide wider temperature operating conditions than elastomeric diaphragm designs.
An integral Stainless Steel filter screen aids in providing long service life. The Series NR has been tested and certified for use on Natural Gas Vehicle Fueling Systems to the rigid standards of the European Regulation ECE R110.
All NR Series Regulators are provided R110 Stamped.
