Data sheet

Precision pressure controller with feedback connection G 1/4", 0,5 to 16 bar, Standard 3.
Item number:
DRF 31-16 FB

Item description
Application:
Precision pressure regulators are used where a very high constancy of the secondary pressure is required with small flow quantities. The good regulation and flow characteristic curve is achieved thanks to the fact that ratio of the membrane to the valve seat surface is very high. The regulator is independent of inlet pressure variations to the best possible extent, does not have any own air consumption and can be used with "normal" filtered compressed air.
Version:
Self-relieving pressure regulator
Materials:
Body: die-cast zinc Z410, diaphragms and seals: FKM
Temperature range:
-10 to +60 °C
Input pressure:
max. 16 bar
Pressure gauge connection:
G 1/4"
Switch panel thread:
M 20x1,5
Media:
Compressed air, neutral gases
Scope of delivery:
Pressure regulator incl. 50 mm pressure gauge
Flow:
550 l/min, secondary vent: 100 l/min
Own air consumption:
none (precision pressure regulator with feedback connection: low own air consumption)
Control accuracy:
± 7.5 mbar
Advantages:
•Automatic venting in the event of overpressure on the secondary side,
•Precise pressure regulation regardless of the pre-pressure,
•No own air consumption,
•Robust design, no microfilter necessary for compressed air
