The BD12 is the 1.5 inch port size version of the BD series precision back pressure regulators. While less commonly used than the larger 2 inch port BD16, the smaller BD12 is used where 1.5 inch pipe sizes are already in use. The BD12 is also useful if overall package dimensions or weight are a concern.
BD Series Back Pressure Regulators are typically used in industrial applications with high flow rates. Competitive valves are often cast from materials (such as carbon steel and cast iron) that do not handle aggressive chemicals and corrode after short periods of use. The BD Series is available in all SS316L and PTFE construction for the most demanding chemical applications.
The BD Series valves are extremely durable and built to last. Since the diaphragm is the only moving part, it is the only part in the valve which can fail. It is replaced easily in a matter of minutes for a very nominal expense, typically less than 10% of the cost of a new valve. Competitive valves have repair kits which cost up to half the price of a brand new valve and take hours to rebuild.
The BD Series are available in pipe sizes from 1.5″ to 4″ and typically in pressure ranges 150 psig and below (high pressure models are also available). They are true 1:1 dome loaded back pressure valves, meaning that 1 unit pilot pressure yields 1 unit upstream pressure. There are many advantages to using our dome loaded design, such as: extremely wide range of Cv with a single unit, frictionless operation with no cracking pressure, and no hysteresis as found in traditional spring loaded regulators.
