Point of Use Regulator

Wall mounting version

The regulator is mounted on a wall console for reducing line pressure to working pressure at a second stage.

In case of maintenance, the regulator can be separated from the shut-off valve to avoid a complete shutdown of the pipeline.

As a standard configuration the point of use regulator will be supplied with shut-off valve, a gauge for working pressure and a precision pressure regulator FR1.
