The Equilibar® back pressure regulator and flow control valve is now available in a sanitary single use design to accommodate the rapidly expanding single use technology (SUT) field in the biopharmaceutical 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 and stainless steel. The polymer body and diaphragms are disposable and are inserted into a stainless steel support housing with wing nut closure for quick and easy assembly.

The Equilibar single use regulator features the same dome-loaded multiple orifice technology as all Equilibar patented products, delivering instantaneous control, frictionless operation and superior precision across exceptionally wide flow rate ranges. Its strengths are particularly well suited to control the transmembrane pressure in tangential flow filtration control applications or cross-flow filtration, and dP control in virus filtration systems.

In addition to pressure control applications, the Equilibar SD 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.

SD Series Specifications:

• Pressure range: 0-4 bar(g) / 0 – 60 psig
• Tubing size: 1/4″ (6.3 mm) to 3/4″ (19 mm) tubing
• Manufactured using USP Class VI HDPE with SS316 housing
