The B42 is a spring loaded self-operated regulator with internal relief option. The B42 features a molded diaphragm, 6:1 lever ratio and a 3/4" vent. The benefit is a lighter more compact unit that provides the power, capacity and relief performance of larger regulators.

The B42R is the internal relief (R) version of the B42 Series. The large 1" internal relief valve provides exceptional relief capacity.
