BDM24 Industrial Back Pressure Regulator

The 2″ BDM16 back pressure regulator is useful for a wide variety of liquid and gas services throughout industry. It is available with female NPT flanged ports (standard), and with integral flanges, ANSI Class 150 or 300 flanges, DIN EN 1092-1 or Tri-clamp flanges. The BDM models are designed to be used at slightly higher-pressure conditions than the BD models, up to 150psig / 10.3 bar(g).

BD Series

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, in contrast, is available in all SS316L and PTFE construction for the most demanding chemical applications. It is also available in Anodized Aluminum, rounding out a family of valves for use across a variety of process conditions.

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 400 psig in some models. They are 1:1 dome-loaded back pressure valves with pilot operation. This means that 1 unit of pilot pressure gas fed into the dome yields 1 unit of upstream setpoint pressure. There are many advantages to the multiple orifice, dome loaded design, including an extremely wide range of Cv with a single valve, frictionless operation with no cracking pressure, and no hysteresis as found in traditional spring loaded regulators.
