STANDARD pressure regulator (volume booster) G 1-1/2", Standard 7
Item number:
DRI 7740
Example illustration
Item description
Application:
A remote controlled pressure regulator is used, when high flow rates are required with a constant pressure. The pressure regulator can also be used at inaccessible locations (e.g. in hazardous or ceiling areas). The setting is made using a pilot pressure regulator that can be placed anywhere. The regulated pressure corresponds to the pressure of the remote controlled bore.
Version:
Self-relieving pressure regulator
Materials:
Body: die-cast zinc Z410 (model series 5 to 8: aluminium), diaphragms and seals: NBR
Temperature range:
-10 to +80 °C
Pressure gauge connection:
G 1/4"
Media:
Compressed air, neutral gases
Scope of delivery:
Pressure regulator without pressure gauge
ATEX:
Operating material without its own potential source of ignition in accordance with Directive 2014/34/EU
Advantages:
•Automatic venting in the event of overpressure on the secondary side,
•High flow at constant pressure,
•Remote-controlled pressure regulation using a pilot regulator (when using a precision pressure regulator as a pilot, it is possible to set the pressure very accurately)
Recommendation:
For best regulation results, please use the precision pressure regulator with feedback connection Type DRF 31-7 FB / DRF 31-16 FB
Warning: Order accessories at the same time!
