The Equilibar back pressure control valve is now available in a sanitary Single Use Design (SD Series) to accommodate the rapidly expanding requirements of BioPharma industry. Single use systems (SUS) 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 Equilibar Single Use back pressure regulator 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.

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

• Pressure range: 0-4 bar(g) / 0 – 60 psig
• Tubing size: 1/4″ (6.3 mm) to 1″ (25 mm) tubing
• Manufactured using USP Class VI HDPE
