R-Series Volume Boosters ♦ Diaphragm type pilot operated regulator High relief flow Outlet pressure up to 300 psig Vacuum service Rapid response option available R-series volume boosters are diaphragm operated, air piloted, self-venting regulators. They are designed for general applications that require superior pressure regulation, rapid response to changing flow demands, and excellent stability. Using QB, BB, or MM series pressure controllers in conjunction with the R-series volume booster gives a precision pressure control package with high forward and reverse flow capacity. If faster response is required, the Rseries can be modified with a special reduced volume bonnet. The R-series volume boosters can also be used in vacuum applications where high flow and precise vacuum control is required.
