R Series Regulator

Brand: Proportion-Air, Inc

The R-Series pilot operated regulators and 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 series pressure controllers in conjunction with the R-Series volume booster gives a precision pressure control package with high forward and reverse flow capacity.

The R-Series pilot operated regulators can also be used in vacuum applications where high flow and precise vacuum control is required.
