The 455-Series is installed using an external sensing line which is connected several feet downstream of the valve outlet. Downstream pressure is set by turning an adjustment screw that increases or decreases spring force on a diaphragm. The downstream pressure applies a force to the diaphragm to compress the adjustment spring. When the system pressure equals the set point, the diaphragm moves downward against the adjustment spring force closing the valve.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWater, Oil, Other Liquids :\u003c\/strong\u003e The B-Series is primarily used for reducing pressure in WATER systems.

These regulators are commonly found in industrial plants, apartment buildings, water supply systems, schools and underground water distribution systems. The soft-seated elastomeric Viton disc has an operating temperature up to 300°F and will produce a Class V shutoff. No external sensing line is required with this style of regulator.\u003c\/p\u003e\u003ch2\u003eSelection \/ Sizing \/ Capacities\u003c\/h2\u003e\u003cdiv style=\"clear: both;\"\u003e\n\u003cp\u003eFrom the Capacity chart, find the inlet pressure and required regulator outlet pressure.
