The FDO8 is a 1″ sanitary back pressure regulator designed for liquid pressure control in the biopharma and sanitary processes. The compact design facilitates a simple process layout.

The FD Series back pressure regulator family is specifically designed as a sanitary regulator for use in biopharma, food, and other applications where there are surface finish, clean-in-place, drainability, or USP class VI material requirements.

Like our other Equilibar® back pressure regulators, the FD Series features ultra sensitive diaphragm-operated back pressure technology capable of controlling pressure with high precision over a wide range of flows. The pilot-controlled, dome loaded design will control the system pressure in a precise 1 to 1 relationship with the pressure applied to the dome. This dome pilot pressure may be provided by a manually adjustable spring loaded regulator or by an electronic pressure regulator for computer control.

The flexible membrane diaphragm is the only moving part. This membrane instantly responds to changes in the system flow rate to accurately maintain the pressure at the desired set point. The FD series is the most accurate and highest resolution sanitary back pressure regulator on the market. The simple design allows for extremely fast disassembly and field repair using low cost rebuild kits.

Contact an application engineer to determine if the FD Series regulator is suited for your specific requirements.
