FAQ: Answering Key Questions about back pressure regulator

SBPR

The SBPR Series sub atmospheric back pressure regulator is designed to provide precise upstream vacuum control.

One example of this could be to introduce a sample gas at a positive pressure into a vacuum chamber. Downstream from this chamber would be the SBPR and a vacuum pump. The positive pressure will build up in the chamber causing the SBPR to open and allow the chamber to return to the vacuum desired. The SBPR will then close, and the process will repeat. The large diameter diaphragm aided by a vacuum assist spring, provides the user with optimum sensitivity for sub atmospheric pressure control.
