The purpose of overcentre valves is to maintain a set pressure opposite a load, keeping it from free-falling. Now, thanks to the new advancements in overcenter valve technology, controlling a load smoothly has become much more easier especially when pumps and actuators become more advanced and, at the same time, directional control valves become more complicated.
In selecting this kind of elements one fundamental parameter to take into consideration is the release characteristic that is based on the direct coherence between the pressure and the flow via the valve. Often unwanted oscillations in applications like crane booms or lifting platforms are caused by over dimensioned flow cross sections or insufficient dampening of these valve types and consequentially all the latest developments in this peculiar domain aim at creating a valve that can unify both sufficient dampening and good responsiveness. This special technical discovery could represent a real help for the needs of customers manufacturing mobile machines. So now many suppliers of valves are trying to do their best to create special products for hydraulic systems in the mobile and fixed sectors: all this items have been projected in order to meet the specific requirements of every type of customer.
