Description
Designed 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
