The BD24 back pressure regulator has a 3 inch port size and is used where accuracy and resolution are important. The multi-orifice design allows the regulator to control accurately even at low flow rates.
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. The thin diaphragm is the only moving part, allowing frictionless operation and easy replacement at 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″ in pressure ranges from 30 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, 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.
