Within a hydraulic system valves VSL they are used to manage sequences of operation of one or more of the actuators through the appropriate setting of the valve. A typical application is the creation of sequences of extension of more hydraulic cylinder, where the cylinder swings out only when the previous one has reached the end of the race. The valve VSL is unidirectional, in the direction of the return flow is free. The valve can work with a maximum recommended flow rates of 40 lpm and pressures up to 350 bar. The run-parts-in-body, it can be installed in-line within the hydraulic system. The body and all external components are made of high-strength steel and subjected to zinc treatment to resist to the action of corrosive agents. The internal components are also made of steel, hardened and ground where necessary to ensure the correct level of performance to the valve.
