Single Use Control Valve for Biopharmaceutical Applications

Flow control and pressure control for single use BioPharma processes

  • image of the Equilibar single use back pressure regulator for biopharma use
The Equilibar back pressure control valve is now available in a Single Use Design (SD Series) to accommodate the rapidly expanding requirements of BioPharma industry. Single use processes require lower cost components that can be sterilized through irradiation and disposed of after use. The patent pending Equilibar SD series is manufactured using USP Class VI polymers that can be sterilized as an assembly. Only the wetted components and diaphragm are disposable, and are inserted into a permanent stainless steel support housing for quick and easy assembly.

The Single Use Equilibar features the same dome-loaded multiple orifice technology as all Equilibar patented products, delivering instantaneous control, frictionless operation, superior precision, and exceptionally wide flow rate ranges. Its strengths are particularly well suited to control the transmembrane pressure in tangential flow filtration control applications.

The Equilibar SD series valves are manufactured and assembled in a class 7 clean room. Each unit is shipped in two hermetically sealed plastic bags. While typically provided unsterilized so that it can be cleaned as part of a larger assembly, the SD series is optionally available sterilized by Gamma radiation.

Equilibar regulators feature ultra sensitive diaphragm-operated back pressure technology capable of controlling pressure with high precision over a wide range of flows. It fully opens in less than 1% overpressure in most applications. The stability of the Equilibar regulator is unmatched in the industry. The graph below shows the performance of a 1/2” single use regulator with water.

In addition to pressure control applications, the Equilibar® valve can be used in on/off applications in Single Use processes. Potential advantages for on/off applications include the simple construction, ease of computer automation, and low pressure drop.
