B-Series

B-Series Regulators

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. 

Controlling Pressure

The B-Series valve reduces downstream pressure of water or gas. This valve does not require an external sensing line and maintains downstream  pressure regardless of inlet pressure. Downstream pressure is set by turning an adjustment screw that increases or decreases spring force above a diaphragm to compress the adjustment spring. When the system pressure equals the set point, the diaphragm moves upward against the adjustment spring force closing the valve.

Design Features

The B-Series regulator has a balanced valve trim allowing accurate control even when incoming pressure fluctuates. The B-Series features a soft-seated elastomeric Viton disc that has an operating temperature up to 300°F and will produce a class V shutoff. Viton Diaphragm, disc and cup packing are rated for 300°F service.
