SDE Hydraulic circuit arallel circuit parallel circuit can be composed using or Q working sections. he outlet section can be with or without port arrangement. Description example: SDE//N(GW-75)ELN/Q-ES/Q-ES/RF-VDC Series circuit: only for l/min (5. US gpm) sections he series circuit is composed using alternately QS and Q working sections, both with S series spool. he circuit starts always with QS working section. he outlet section depends on total number of working sections: if it is even, the outlet section must have port open, if it is odd, the outlet section must have port open.
