Typical Applications

The B-Series Pressure regulators are primarily used for reducing pressure in water systems. Also suitable for air, oil, and other liquids or gasses. The B-Series offers much higher capacities than the O-Series. These regulators are commonly found in industrial plants, apartment buildings, schools, and water distribution and supply systems.
