Exemplary representation: High-pressure pressure regulator - Standard-HD Exemplary representation: High-pressure pressure regulator - standard HD, type DR 8740 & DR 8840 Schematic symbol

Version:

Self-relieving pressure regulator

Materials:

Body: brass (DR 8740 and DR 8840: gravity die cast aluminium), diaphragms and seals: NBR

Temperature range:

-10 to +90 °C

Input pressure:

max. 40 bar

Pressure gauge connection:

G 1/4"

Switch panel thread:

DR 1140: M 20x1,5, DR 3340: M 28x1,5

Media:

Oiled and unoiled compressed air, neutral gasses

Scope of delivery:

Pressure regulator incl. 50 mm pressure gauge

Optional:

Other regulation ranges: 0.5-3 bar -3**, 0.5-6 bar -6, 0.5-16 bar -16, 0.5-25 bar -25, lockable (DR 8740 and DR 8840) -K

Advantages:

•Automatic venting in the event of overpressure on the secondary side
*Input pressure gauge 0 - 60 bar, **not available for types DR 8740 and DR 8840, ***measured at P1 = 8 bar, P2 = 6 bar, Delta p = 1 bar
