New Brochure on FD Series of Sanitary BPRs for BioPharma

Equilibar’s FD Series of sanitary back pressure regulators features an innovative dome-loaded technology to meet the most demanding pressure control challenges in the BioPharma industry.

The FD Series offers the following specific advantages for sanitary applications:

  • 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

For more information, we invite you to review our new FD Series Brochure, which provides performance comparisons, options, schematics, and more.

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.

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 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.

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 model is 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.

New White Paper Focuses on Flow Control Setup at Integrated Lab Solutions

A new white paper explains how an Equilibar® can be used in combination with a mass flow sensor to provide reliable flow control for particularly difficult research applications. While Equilibar’s ability to provide excellent pressure control is well known, fewer scientists and engineers are familiar with using it for flow control, making the paper especially […]
