Duplomatic DS5-RK/12N-A110K1 NG10 directional control valve
DS5-RK/12N-A110K1 is a direct acting solenoid operated directional control valve for NG10 / CETOP 05 subplate mounting. Spool RK provides 4/2 mechanical detent. With the solenoids de-energized: Last selected working position retained by mechanical detent. Two solenoids; mechanical detent, without centering springs.
The maximum pressure at P, A and B is 320 bar. For this standard AC version, the T-port limit is 140 bar and catalogue maximum flow is 120 l/min. Actual permissible flow depends on spool, pressure and circuit arrangement; check the operating-limit curves in the catalogue. This product is the standard version without the optional Y external drain.
Supply: 110 V AC / 50 Hz; 120 V AC / 60 Hz. Series 12 identifies the AC version. The valve has 2 AC solenoids and a standard integrated manual override. K1 connectors are not included. NBR seals suit HL/HM mineral hydraulic oil. The CAD view and DWG correspond to the external two-solenoid AC construction; the selected spool function is defined by the ordering code and hydraulic symbol.
IMPEX CONNECT supports international B2B sourcing of DS5-RK/12N-A110K1 for industrial hydraulic systems. Match the ISO mounting interface, spool function, return condition, voltage and T-port pressure when selecting a replacement. Availability and delivery time are confirmed on request.
Install the RK valve with its longitudinal spool axis horizontal. The two working positions are mechanically retained; there is no spring-centered neutral position.
