Precision pressure regulators, remote controlled (volume booster), 6500 l/min

Remote-controlled precision pressure regulators are used when high flow values are required at a constant pressure. The pressure regulator can also be used at inaccessible places (for example, in danger zones or the roof areas). Setting is done by means of a pilot pressure regulator that can be placed anywhere at will. The regulated pressure corresponds to the pressure applied at the remote control borehole and is maintained with high precision.

Operating material without its own potential source of ignition in accordance with Directive 2014/34/EU

•Automatic venting in case of overpressure on the secondary side from large vent hole (G 3/8") with up to 800 l/min,
•High flow rate at constant pressure,
•Remote pressure control by a pilot regulator (when using a precision pressure regulator with feedback connection as pilot, a very precise pressure setting is possible),
•Fine control of the pressure independent of inlet pressure and flow rate,
•Can be used up to -35 °C

For best regulation results, please use the precision pressure regulator with feedback connection Type DRF 31-7 FB / DRF 31-16 FB

This device is supplied without a pressure gauge. We recommend ordering a suitable pressure gauge separately.
