RG2712/13 Air Piloted Regulator

Brand: Proportion-Air, Inc

The RG2712/13 series of pilot operated regulators fit all the places where standard catalog pressure regulators fall short.

The RG2712/13 series is available in models to act as a volume booster in very low pressure applications or as ratio operated regulators for very high pressures. Most nonstandard applications can be matched to an RG series pilot operated regulator.

All RGs are able to be pilot operated with Proportion-Air’s electronic air pressure control valves. With this combination the Proportion-Air electronic pressure regulator provides a low flow precisely controlled pressure signal to the pilot section of the RG regulator.

The RG regulator acts as a volume booster and converts the low flow precision air pressure signal into a much higher flow at the same pressure.

High flows can be controlled with electronic precision in this manner.
