All data are considered to be unbinding reference values. We accept no liability for data selection that is not confirmed in writing. Pressure data refer, if not otherwise indicated, to liquids of Group II at +20°C. 8 Pressure booster/Pressure limiting valves Application: The pressure booster increases the input pressure to the value set on the control valve. The output pressure can measure max. four or 2 two times the input pressure, but can never exceed the max. output pressure. Should an in- dividual consumer (clamping cylinder etc.) be operated with a pressure higher than the standard network pressure, the pressure booster can accordingly increase the supply pressure for this single consumer. An installed pressure regulator maintains a constant working pressure (with less pulsation). Advantages: High energy saving and no electrical energy necessary directly on consumer. For a further consumer, it is not necessary to pretension the entire compressed air network to a higher level. Installation recommendation: In order to reduce the pressure pulsation on the secondary side, we recommend crea- ting an additional volume in the form of a container. If the volume of the downstream air line is not sufficient, then the following containers should be integrated behind the pressure booster. Pressure booster Container volume DUE 60 A 1.3 to 3 litres DUE 230 A 10 to 12 litres DUE 1000 A 20 to 25 litres DUE 1600-16 A 30 to 50 litres DUE 1900 A 50 to 100 litres Media: Filtered, unoiled compressed air Installation position: Horizontal Temperature range: +5°C to max. +50°C Pressure boosters pneumatic up to 20 bar Type DUE 60 A 4 : 1 2 - 20 bar 60 l/min G 1 / 4 “ R 1 / 8 “ DUE 230 A 2 : 1 2 - 20 bar 230 l/min G 1 / 4 “ R 1 / 8 “ DUE 1000 A 2 : 1 2 - 10 bar 1000 l/min G 3 / 8 “ R 1 / 8 “ DUE 1600 A 2 : 1 2 - 16 bar 1600 l/min G 1 / 2 “ R 1 / 8 “ DUE 1900 A 2 : 1 2 - 10 bar 1900 l/min G 1 / 2 “ R 1 / 8 “ MW 2527 MW 2527 MW 1640 MW 2540 MW 1640 Check valve Re g ulator A m plifier cha m ber A Actuatio n cha m ber A way-valve E OUT Check valves Output = hi g h pressure A m plifier cha m ber B Actuatio n cha m ber B Pisto n B i n put = n etwork pressure IN 1 2 3 4 If your network pressure on P1 is partially higher than the pressure in accu- mulator P2 (while the pressure booster builds up the pressure), we recom- mend the system structure as shown in the circuit diagram on the right.

Please note: The greater the pressure increase of P1 to secondary P2 set at the regulator, the lower the available volume flow rate, such as the DUE 230 A, which achieves a 100 litre per second supply amount at 8 bar output pres- sure if the input pressure is 5 bar. We would be happy to provide you with the flow-rate characteristics if needed. This will save you time during the increasing of the working pressure!

Depending on the flow performance, the actual pressure at the pressure input side can be hig- her by the value specified for overpressure. Warning: Although it is si- milar in function, this valve does not replace the safety valve and cannot be used as a pressure regulator!
