Item description
Application:
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.
Version:
Precision pressure reducer, reversible (with secondary relieving) Collective relieving through G 3/8" borehole)
Materials:
Body: die-cast zinc Z410, diaphragms and seals: NBR
Temperature range:
-35 to +60 °C
Input pressure:
max. 16 bar
Pressure gauge connection:
G 1/4"
Own air consumption:
1.7 l/min at 6 bar outlet pressure
Control accuracy:
± 2.5 mbar
Control connection:
G 1/8"
Media:
fine-filtered compressed air (5 µm) & neutral gases, oil-free
Flow:
6500 l/min, secondary relieving: 800 l/min
ATEX:
Operating material without its own potential source of ignition in accordance with Directive 2014/34/EU
Advantages:
•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
Recommendation:
For best regulation results, please use the precision pressure regulator with feedback connection Type DRF 31-7 FB / DRF 31-16 FB
Warning:
This device is supplied without a pressure gauge. We recommend ordering a suitable pressure gauge separately.
