Duplomatic DT03-2H/11N-R220K1 NG6 poppet directional valve
DT03-2H/11N-R220K1 is a direct operated solenoid poppet valve with a conical seat, 2/2 configuration and spring return. Scheme 2H provides 2/2 normally open. De-energized: P connected to T. Energized: P and T blocked. The two-way design provides bidirectional sealing.
Maximum operating pressure is 250 bar. This version follows operating-limit curve 1, with flow up to 25 l/min; permissible flow decreases with pressure. The family rating of 25 l/min does not apply to every execution. The R220 coil is for a 220 V AC, 50/60 Hz supply with a bridge rectifier in a type D connector or an external rectifier. Do not connect the coil directly to AC. The connector and rectifier must be ordered separately.
During switching, all valve flow paths are interconnected. With accumulator supply or high-delivery pumps, use suitable orifices on the accumulator side to limit flow to 12 l/min, while respecting the version-specific operating limits. This standard product has no optional D08/D10 port-P orifice.
NBR seals suit mineral hydraulic oil. The primary CAD view and downloadable DWG represent the external side-A construction shared by 3C, 3D, 2E and 2H in the catalogue. The supplied CAD reference is D24; the ordering code specifies the hydraulic function and electrical equipment.
