SDO1 Single Use Valve

The Equilibar® SDO1 valve is a single use back pressure regulator (BPR) with 1/8″ hose barb fittings and a Cv range between 1E-04 and 0.06. It controls pressure up to 60 psig / 4 bar(g) with millibar sensitivity.

SD Series Single Use Back Pressure Regulators

Equilibar SD Series Single Use Back Pressure Regulators are specifically designed for single use technology (SUT) and hybrid systems in the biopharmaceutical industry. They can be used to regulate pressure or be set up for use in closed loop flow control applications.

Like the other Equilibar back pressure regulators, the SD Series features ultra sensitive diaphragm-operated back pressure technology capable of controlling pressure with high precision over a wide range of flows. The pilot-controlled, dome loaded design will control the system pressure in a precise 1 to 1 relationship with the pressure applied to the dome. This pilot pressure may be provided by a manually adjustable spring loaded regulator or by an electronic pressure regulator for accurate computer control.

The flexible membrane diaphragm is the only moving part in any Equilibar back pressure regulator. This membrane instantly responds to changes in the system flow rate to accurately maintain the pressure at the desired setpoint. The SD series is an award-winning, revolutionary design in single use pressure control.

The SD Series BPR is manufactured using USP Class VI polymers and stainless steel. The consumable valve body made of polymer is inserted into a stainless steel support housing with wing nut closure for quick and easy assembly. The SD injection molded, consumable valve body is assembled and bagged in an ISO 7 clean room. The polymer valve bodies are also tested for conformance to USP 788 and USP 85. A full certification package is available for every order.
