Order example and flow pattern symbol LP 125-12 / D4-C5 Hydraulic power pack with directly mounted directional seated valve type VB 11 acc. to D 7302 Order example and flow pattern symbol LP 125-16 / B4 - VB 11LP - HHH - 1 1. General information ' Hydraulic power pack without connection block (retrofit) or with connection block for direct pipe connection ' Hydraulic power pack with connection block and directly mounted directional seated valve bank. The connection blocks are available with/without pressure limiting valve. There is usually pressure limiting valve necessary for the hydraulic side, when the pneumatic pressure is set at the pressure reducing valve of the pneumatic maintenance unit accordingly to the hydraulic consumer specification. The pump will automatically come to a stand-still and restart depending on the pressure level at the hydraulic side. A connection block with a pressure limiting valve has to be utilized when a specific pressure on the hydraulic side must be maintained without altering the pressure on the pneumatic side e.g. necessary when several consumers are driven from one pneumatic source. Drawback is that the pump will run permanently with all excess delivery being returned to the tank via the pressure limiting valve on the hydraulic side The pump will come to a stop only when the pneumatic side is cut-off via a on/off valve.

Observe the max. pressure rating of the directly mounted directional valve banks it might be rated lower than 700 bar. 3) May be used also as idle circulation valve (approx. 5 bar) when the prop. soleid is deenergized. Idle circulation circuits via soleid actuated valves may be useful for frequently changing load/-load periods within one cycle, where it is t practical to start and cut-off the pump for seconds only. In this case the pump will be cut-off after the cycle has been completed 4) The figures in brackets represent the approx. consumable volume, after which the float switch triggers a signal (table 1b). 5) Only avail. for tank B4 and B10
