Fisher™ Type B NG Residential Regulators
Type B NG residential regulator is a direct-action, spring-loaded regulator, with high performance and reinforced safety features.
It provides pressure reducing control in a variety of residential, commercial and industrial applications for a variety of gaseous fluids. A shut-off valve cuts off the gas flow in the case of excessive flow, or when the outlet pressure drops below the set point (high gas demand or broken line) or in the case of inlet pressure dropping below the set point (network pressure drop or pipe damage). The regulator can be manually reset after the safety function trips. The regulator is factory preset. Type B6 NG is interchangeable with the current angle-shaped Type B6 N (same key dimensions).
