The BDM12 has the 1.5 inch port size like the BD12 model, but can withstand a higher pressure. It is only available in the Stainless Steel version and may be used for pressures up to 120 psig (8.3 bar(g)).
BD Series Back Pressure Regulators are designed for use 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. With the diaphragm as the only moving part, maintenance of the BD regulator can be performed quickly on site 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 is available in pipe sizes from 1.5″ to 4″ in pressure ranges up to 150 psig. 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, including 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.
