Equilibar offers fluid control valves designed 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 their useful life. Single-Use systems are an alternative to stainless steel systems to avoid cross-contamination and lengthy CIP validation. Equilibar single use valves are designed for precision control and can help optimize single use biopharmaceutical processing, saving overall cost.<\/p>

Single Use Valve<\/h3>

The Equilibar\u00ae dome loaded multi-orifice valve technology is now available in a single use back pressure regulator and control valve. The patent pending Equilibar SDO Series valves are manufactured using USP Class VI polymers and stainless steel. The disposable polymer body is inserted into a stainless steel support housing with wing nut closure for quick and easy assembly. The Equilibar SDO is a revolutionary design for single use bioprocess control and can be used in pressure or flow control applications in place of a standard pinch valve where accurate results are required.<\/p> Contact Us to learn more about SDO<\/a>

Alternative to a Single Use Pinch Valve<\/h3>

Single-Use Pinch valves use external mechanical compression over existing product tubing to control flow and pressure through a single-use process line. The Equilibar single use valve is a very precise alternative to a pinch valve. Its award-winning design allows it to be configured for precision pressure regulation or closed loop flow control. Compared to a pinch valve, the SDO single use back pressure regulator responds to process fluctuations and setpoint changes more quickly.<\/p>

Applications<\/h3>

The Equilibar SDO delivers process advantages in many single use applications where pressure and flow are critical factors such as tangential flow filtration, disc stack centrifuge, buffer delivery in chromatography, and WFI point of use flow control.<\/p>

How it Works<\/h3>

The SD single use regulator features Equilibar’s patented dome-loaded multiple orifice technology<\/a> delivering instantaneous control, frictionless operation and superior precision across exceptionally wide flow rate ranges. The stainless steel housing is designed as a permanent part of the process and connects to a dome pilot pressure supply. The disposable body is sold in a pre-sterilized state and comes ready for sterilization up to 50 kGy. See Sample Certificate of Conformance.<\/a> <\/p>

Once assembled, simply apply a pressure to the pilot port in the dome of the Equilibar SDO valve equal to the desired setpoint and the valve does the rest. This pilot pressure forces the upper flexible diaphragm down onto a field of orifices. A rise in inlet pressure lifts the diaphragm up to allow excess pressure to be relieved through the outlet orifices. Similarly, a loss of pressure at the inlet causes the diaphragm to be pushed closer to the orifices, restricting flow and rebuilding pressure at the inlet.<\/p>
