Duplomatic DSE3B-A01SA/10N-D12K1 proportional directional valve
DSE3B-A01SA/10N-D12K1 is a direct operated proportional directional valve for continuous control of hydraulic actuator direction and speed. This NG6 / CETOP 03 execution has a open centre A spool, 1 solenoid on side a, 2 positions, spring return, 12 V DC proportional coils, K1 electrical connections and NBR seals.
Nominal spool flow is 1 l/min at Δp 10 bar P→T. The overall valve maximum is 40 l/min; actual flow depends on pressure drop and coil current. Maximum operating pressure is 350 bar at P, A and B, and 160 bar at T. These DSE3B limits must be checked when replacing another valve series.
Manual override: Integrated pin, standard. Use a suitable current-controlled power supply or external proportional amplifier; catalogue examples include EDC-142 / EDM-M142. Maximum current is 1.88 A per coil. Nominal coil voltage alone is not a proportional command signal. K1 connectors are included in the catalogue supply. NBR seals are intended for HL/HM mineral hydraulic oils.
The standard body has black phosphating. The CAD illustration and DWG correspond to the selected SA K1 construction and standard pin override; the ordering code identifies the spool and voltage. IMPEX CONNECT supports international B2B sourcing of DSE3B-A01SA/10N-D12K1 for industrial hydraulic systems. Confirm the hydraulic circuit, mounting dimensions and amplifier compatibility; availability and delivery time are confirmed on request.
