High-performance precision pressure regulator, G 1/4", 0,05 to 4 bar
Item number:
FDR 02-4
Item description
Application:
High performance precision pressure regulators are used in order to adjust an extremely accurate pressure - regardless of pre-pressure and flow performance. It is used for example for control and regulation units in process engineering, which has the highest pressure stability requirements.
Version:
Precision pressure reducer, reversible (with secondary relieving), (model series 2: collective relieving through 3/8"-borehole)
Materials:
Body: die-cast zinc Z410, diaphragms and seals: EPDM (model series 2: NBR)
Temperature range:
-10°C to max. +60°C (model series 2: -35°C to max. +60°C)
Input pressure:
max. 16 bar
Pressure gauge connection:
G 1/8" (model series 2: G 1/4")
Switch panel thread:
M 12x1 (series 2: M 20x1.5)
Own air consumption:
1.7 to 2 l/min
Control accuracy:
± 2.5 mbar
Media:
fine-filtered compressed air (5 µm) & neutral gases, oil-free
Flow:
900 l/min (model series 2: 6500 l/min), relief system: 200 l/min (model series 2: 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 (series 2: up to 800 l/min),
•High flow rate at constant pressure,
•Fine regulation of pressure independent of inlet pressure and flow rate,
•Series 2: can be used down to -35 °C!,
•Supplied exhaust air (G 3/8") for secondary venting (series 2)
Warning:
This device is supplied without a pressure gauge. We recommend ordering a suitable pressure gauge separately.
