Functional description, section Housing Spool 3 Check valve 3 5 4 Operating element 5 Secondary valve 6 lug 6 4 4 he S control block basically comprises of an inlet element, directional valve elements and an outlet element. he control blocks are designed to the 6-way principle and comprises of a housing (), control spool (), load holding check valve (3), spool actuation and return system (4), cavities (5) for the secondary pressure valves or relief/anti-cavitation valves, as well as anti-caviation valves or plugs (6). With all of the spool axes in their neutral position the flow passes via the bypass channel at zero pressure to tank. If one of the control spools is actuated then the connection from the pump to the actuator is opened via the fine control grooves, whilst the bypass is throttled by fine control grooves. If the pump pressure exceeds the actuator pressure, the pressure fluid starts to flow over the check valve to the actuator. With further movement of the control spool () the volume of fluid is increasingly diverted from the bypass channel to the actuator (fine control). he spool stroke is divided into three phases: overlap (leak-free in the neutral position), fine control range (flow and pressure), residual stroke (fully open). Due to the large fine control range of the spool stroke it is possible to sensitively control the actuators.
