Olsbergs control systems are installed in more than 20,000 machines. These are mainly truck loader cranes and forestry cranes.
The valves are load-sensing and pressure compensated. Load-sensing technology in combination with variable pumps provide energy-efficient hydraulic systems. Olsbergs valves are equipped with a unique positioner, or actuator, allowing for mechanical feedback of the valve spools. The valve can be controlled very accurately without affecting the flow.
The valves feature improved design and capacity, with a Monoblock design for coping with high pressure. They operate with a maximum pump pressure of 450 bar and at a flow of 300l/min maximum. The valve Q200 has two levels; the lower level houses the pressure compensator and shuttle system and the upper level houses the valve spools.
However, the Q300 valve is equipped with a third level at the top level, which houses shock relief valves and anti-cavitations valves. Olsbergs offers a number of specially adapted inlet and outlet sections of modular design for connection to different types of hydraulic systems and pumps. For example one type of inlet section is designed to provide pressure compensated flow to e.g. an outrigger valve, and one type of outlet section has an integrated pressure reducer and filter unit.
The company develops hydraulics and electronics in parallel to provide efficiency, speed and precision.
