Product Description
FDO4 Sanitary Back Pressure Regulator

FDO4 Sanitary Back Pressure Regulator

The FDO4 is a lower-flow back pressure regulator with 1/2″ sanitary clamp connections. It is ideally sized for liquid blending applications of chemical additives in the range of 1 ml/minute to about 3000 ml/minute. This model is typically outfitted with PTFE or USP Class VI EPDM diaphragms. The FDO4 is a lower-flow back pressure regulator with 1/2″ sanitary clamp connections.

FD Series
The FD back pressure regulator family is specifically designed as a sanitary regulator for use in bio-pharma, food, and other applications where there are surface finish, clean-in-place, drainability, or USP class VI material requirements. Also known as pressure sustaining valves, the FDO series is typically manufactured from polished stainless steel 316L and enhanced PTFE as the only wetted parts. A 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 FDO is a pilot operated design and will control the system pressure in a precise 1 to 1 relationship with the pressure applied to the pilot port. This pilot pressure may be provided by a manually adjustable spring loaded regulator or from an electronically controlled pressure regulator. The FDO’s simple design allows for extremely fast disassembly and field repair using low cost rebuild kits.
