2 SD6 - DLS7 SD6 Simple, compact and heavy duty designed sectional valve from to sections for open and closed center hydraulic systems. H Fitted with a main pressure relief valve and a load check valve on every working section H vailable with parallel, tandem or series circuit. H Optional power beyond port. H wide variety of port and circuit valves. H vailable manual, pneumatic, hydraulic, electro--hydraulic, and remote with flexible cables spool control kits. H Diameter 6 mm (.63 in) interchangeable spools. DLS7 hey are for systems with fixed displacement pumps (open center version), or variable displacement pumps (closed center version), with Load--Sensing signal on each working section to pump flow control valve control. H Load--indipendent flow control. H orts valves and side control kits are the same of SD6 directional valve. H L.S. signal connections on every working section. dditional information his catalogue shows the product in the most standard configurations. lease contact Sales Dpt. for more detailed information or special request.
