Volume boosters are found on page 339 & 348 DRF 31-7 FB* G 1 / 4 “ 0.2 - 7 bar 0 - 10 bar * low own air consumption Application: Precision pressure regulators are used when in the case of small flow quantities, a highly constant secon- dary pressure is required. The very good control and flow characteristics are achieved due to the fact that the diaphragm is very large in proportion to the valve seat surface. The regulator is largely independent of the input pressure oscillati- ons, does not have its own air consumption and can be used with “normal” filtered compressed air. Version: Resettable (with relieving system) Materials: Body: Zinc die-casting Z410, diaphragms and seals: FKM Temperature range: -10°C to max. +60°C Input pressure: Max. 16 bar Flow: 550 l/min, relieving system: 100 l/min Own air consumption: None Control accuracy: ± 7.5 mbar Pressure gauge connection: G 1 / 4 “ Media: Oiled and unoiled compressed air, non-toxic and non-flammable gases Switch panel thread: M 20 x 1.5 Advantages: Ÿ Automatic venting in the event of overpressure on the secondary side. Ÿ Precise regulation of the pressure regardless of pre-pressure. Ÿ No own air consumption Ÿ Robust design, no microfilter necessary for the compressed air 82 129 148 8 6 4 2 0 160 320 480 640 Qn l/min p 2 [bar] p 1 = 8 bar 800 BW 30 BW 30 BW 30 BW 30 BW 30 ü application example type DRF 31-7 FB High performance precision pressure regulators up to 6 500 l/min 58 107 124 82 159 200 8 6 4 2 0 1200 2400 3600 4800 Qn l/min 6000 p 2 [bar] p 1 = 5 bar 200 400 600 800 1000 0 2 4 6 8 p2 [bar] p1 = 10 bar Q n [l/ m i n ] 8 6 4 2 0 100 200 300 400 Qn l/min p 2 [bar] p 1 = 5 bar 500 FDR 02 (0.05 - 2 bar) FDR 03 (0.05 - 3 bar) Type Thread Model series 1, pressure gauge connection G 1 / 8 “ FDR 02-2 G 1 / 4 “ 0.05 - 2 bar FDR 02-4 G 1 / 4 “ 0.05 - 4 bar FDR 02-7 G 1 / 4 “ 0.05 - 7 bar Model series 2 , pressure gauge connection G 1 / 4 “ FDR 03-3-14 G 1 / 4 “ 0.05 - 3 bar FDR 03-7-14 G 1 / 4 “ 0.05 - 7 bar FDR 03-3-38 G 3 / 8 “ 0.05 - 3 bar FDR 03-7-38 G 3 / 8 “ 0.05 - 7 bar FDR 03-3 G 1 / 2 “ 0.05 - 3 bar FDR 03-5 G 1 / 2 “ 0.05 - 5 bar FDR 03-7 G 1 / 2 “ 0.05 - 7 bar FDR 03-10 G 1 / 2 “ 0.05 - 10 bar BW 20 BW 20 BW 20 BW 30 BW 30 BW 30 BW 30 BW 30 BW 30 BW 30 BW 30 ü Order accessories at the same time! type model series 1 type model series 2 flow FDR 03 (0.05 - 3 bar) venting Liquid seals, gaskets & tapes from page 549 PU, PA, PTFE and PE hoses from page 192 Mounting bracket Pressure regula. range Pressure gauge display Mounting bracket Pressure regula. range Suitable pressure gauges can be found on page 372. 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 en- gineering, which has the highest pressure stability requirements. Version: Resettable (with relieving system), (model series 2: through G 3 / 8 “ borehole) Materials: Body: Zinc die-casting 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 Flow: 900 l/min (model series 2:6500 l/min), with relieving system: 200 l/min (model series 2: 800 l/min) Own air consumption: 1.7 to 2 l/min. Control accuracy: ± 2.5 mbar Media: Unoiled, finely filtered compressed air (5 µm), non-toxic and non-inflammable gases Switch panel thread: M 12 x 1 (model series 2: M 20 x 1.5) ATEX: Operating material without its own potential source of ignition in accordance with Directive 2014/34/EU Advantages: Ÿ Automatic venting in the event of overpressure on the secondary side (model series 2: up to 800 l/min) Ÿ High flow at constant pressure Ÿ Most precise pressure regulation regardless of the pre-pressure and flow performance.
