The Sun Hydraulics DNCADCV912N (DNCADCV912N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve ensures a closed transition between positions, minimizing oil loss during shifting which is crucial in maintaining the efficiency of pilot control circuits. With a capacity based on port 3 as the inlet and port 1 as the tank, the DNCADCV912N can handle a flow rate of up to 8 gpm (30 L/min) and is capable of operating at pressures up to 5000 psi (350 bar). The valve is distinguished by its robust solenoid tube assembly that is fatigue rated for high-pressure service and its wet armature design. The latter feature allows the working fluid to surround the armature, aiding in heat dissipation but necessitating consideration of fluid characteristics due to potential breakdowns from prolonged coil energization. It accommodates various coil termination and voltage options, enhancing its adaptability across different system requirements. Additionally, this model incorporates Sun's floating style construction which mitigates risks associated with internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The DNCADCV912N also supports reverse flow; however, optimal performance under such conditions is not guaranteed. This valve's compact design includes a manual override feature requiring minimal force and offers quick response times typical at around 50 ms. Its maximum valve leakage at operational pressure does not exceed 10 in\u00b3/min at 3000 psi. The DNCADCV912N's reliability and performance are further ensured by interchangeable coils compatible with other Sun Series 1 solenoid products and various environmental protection options available through additional weatherized coils and kits.

This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.
- Valve capacity is based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- A wide variety of coil termination and voltage options are available, with and without surge protection. See the CONFIGURATION section.
- The solenoid's unique magnetic design results in a high efficiency solenoid, yielding high spool actuating force per Watt expended, leading to reliable valve shifting.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Coil connector options offer ratings up to IP69K. See individual coil product pages for details. Additional weatherized coils and kits are available for more complete environmental protection.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
