Product Description

FDO6 Sanitary Back Pressure Regulator

The FDO6 is a sanitary back pressure regulator with 3/4″ sanitary clamps. With a Flow Coefficient (Cv) of 4.0, it is ideal for liquid flow rates between 0.1 and 50 gallons/minute.

FD Series Sanitary Valves

The FD Series Sanitary regulators are specifically designed for use in biopharma, food, and other applications where there are surface finish, clean-in-place, drainability, or USP class VI material requirements. They can be used to regulate pressure or set up for closed loop flow control.

Like the 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 accurate 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 setpoint. 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. It’s compact form facilitates a simple process layout.

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