  • Sanitary regulator for Interphex

Equilibar invites all BioPharma and related industry customers to see our sanitary back pressure regulators by visiting us at InterPhex. We’ll be in Booth 3473 in New York City’s Javits Center.

Engineers Ryan Heffner and Michael Collins will be on hand to explain the technology behind Equilibar’s FD Series of back pressure regulators. Developed in direct response to BioPharma’s unique requirements, the FD Series offers the following specific advantages:

  • Easily automated with manual or electronic control
  • Responds in milliseconds to accurately maintain pressure
  • USP Class VI wetted materials
  • Crevice free / drainable design
  • Rebuilds in minutes
  • Compact actuation

All of Equilibar’s back pressure regulators feature patented technology based on a dome-loaded, multiple orifice design that is capable of holding pressure stable across incredibly wide flow rate ranges. Unlike traditional spring-loaded regulators and valves, Equilibar’s unique design has only one moving part–the wetted diaphragm–which seals directly across the polished array of orifices.

The valve seats are inherently crevice-free and can be flushed with clean-in-place solution, steam or water. They are made of electro-polished SS316L and are also available in Hastelloy C276. USP Class VI EPDM or PTFE diaphragms are typically used in BioPharma applications.

Equilibar’s FD Series also includes options for angled design and tube stubs for welding. Sanitary Tri-Clamp end fittings are standard. Units are rated up to 150 psig (10 bar) and can withstand the high temperatures of Steam-In-Place at 135C.

The FD Series is being successfully deployed in US BioPharma plants to control process liquids in demanding applications, such as wide low-to-high flow ranges and low set-point pressures. In one specific application, the 1” FDO8 and FDO16 models are used downstream of a Coriolis flow meter to hold the discharge pressure to 3 psig in order to inhibit bubble generation inside the sensitive instrument.


We invite you to visit our booth to learn more. Or, if you’d like to speak with Ryan or Michael before InterPhex, feel free to email them at or call 828-650-6590.
