Equilibar Announces New Sanitary Valves to Accommodate Extremely Low Flow Processes and Smaller Process Equipment

Superior precision now possible for more pharmaceutical, food & other sanitary applications

Equilibar has introduced an expansion of products in their popular FDO series of sanitary fluid control valves and back pressure regulators. These new products will provide unmatched precision for biopharmaceutical and other aseptic processes that have extremely low flow rate ranges.

The new FDO2 valve with ¼ inch ports and FDO3 with ⅜ inch ports were introduced to market to serve our customers looking for superior control at lower Cv values,” said Megan Cider-Elm, Life Sciences Product Director for Equilibar and Steriflow Valve. “They open up opportunities for exceptionally precise control for low flow systems as well as offering valves that have the same connection sizes as process lines on smaller process equipment.

Technology behind the new valves

All Equilibar® FDO valves feature a revolutionary multi-orifice diaphragm-operated technology capable of controlling pressure with unmatched precision over a wide range of flow rates. They are pilot-controlled, allowing for easy automation, and are particularly well suited for flow chemistry and other challenging sanitary applications.  A thin, supple membrane is the only moving part, responding instantly to changes in the system flow rate to accurately maintain the pressure at the desired set point. The compact and simple design allows for fast disassembly and maintenance, facilitating an elegant process layout.

The FDO valves are specifically designed for use in biopharma, food, personal care and other applications with requirements for surface finish, clean-in-place, drainability, or USP class VI materials.
