1 Seat Valves Series SVH0 ctuators are shut-off with virtually zero-leakage, even over a longer period of time Particularly suitable for mobile machines, thanks to the low-weight design and small dimensions Can be used as independent valve blocks, or can be at-tached to the L.8S series of proportional directional valves With suitable upstream control valves, all actuators con-nected to the blocks can be proportionally operated dditional auiliary functions can be implemented Description Series SVH0 low-weight (aluminium) valve blocks feature seat valves and are used to control single or double acting cylinders. They are applied where etremely low levels of leakage are required. The design is based on a direct acting, solenoidoperated / seat valve that seals in both directions. The valves close the flow path to or from hydraulic actuators with virtually zero leakage. Where double-acting actuators are to be controlled, the circuit must include a -position directional valve situated before the seat valves. In its mid-position, this valve must connect the service ports to tank. The SVH0 seat valves are available as: Self-contained monoblocks, with add-on sections Monoblocks for attaching to the L.8S series of proportional directional valves Intermediate and end sections for assembling customerspecific valve blocks.
