The hydro-hydraulic proportional valve block of Olsbergs, removed from the HIAB crane, is suitable for e.g. crane use, replacement parts for a similar system or for various hydraulics projects.The ventilation system has four hydraulic functions and electro-hydrical proportional control.Possibility also for Scanreco radio control! Electrohydraulic positioners may be controlled directly by an appropriate PWM power controlled radio control system. This requires ensuring correct control flows, connections and compatibility.We also have a new Scanreco radio control system available for an additional price. Technical informationManufacturer: Olsbergs, SwedenOrigin: HIAB craneDimension number: 3967328Type: Electrohydraulic proportional valveVent functions: 4 unitsHydraulical work connections: 8 units (A/B)Electrical control: PWM power controlled positionorsControl units: 2 units of Ols Bergs electric control modules (based on images DA14)Control module operating voltage: 24 V DCMhdability We also have another 4-karaile Olsbergs valve block.With two valve systems, it is possible to build an 8-function radio-controlled hydraulic system, for example with an 8 lever Scanreco Maxi controller.The other valve block and Scanreko radio control system are available separately for an additional price.
