The Sun Hydraulics DNCADWN712N (DNCADWN712N) 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 features a closed transition between positions, minimizing oil loss during shifting\u2014a crucial aspect in pilot control circuits. The valve operates effectively with a capacity of 8 gpm/30 L/min and can handle maximum operating pressures up to 5000 psi/350 bar. Its robust design includes a solenoid tube assembly rated for fatigue at the same pressure level. Key to its functionality is the wet armature design where the working fluid surrounds the armature; this setup requires consideration of fluid characteristics since prolonged coil energization could lead to fluid degradation. The DNCADWN712N is compatible with EPDM seals specifically for phosphate ester fluids while avoiding exposure to petroleum-based substances which could damage these seals. This model offers versatility through various coil termination and voltage options, including configurations with surge protection. Coils are interchangeable within Sun's Series 1 solenoid products and can be mounted in either direction on the tube. The environmental resilience of the coils is enhanced by options such as weatherized kits, achieving ratings up to IP69K for certain connectors. The DNCADWN712N incorporates Sun\u2019s floating style construction which reduces risks associated with internal parts binding due to installation or machining inconsistencies. It also features a manual override function requiring minimal force and offers rapid response times typically around 50 ms. Switching frequency capabilities reach up to 15,000 cycles per hour, ensuring reliable performance even under intensive operational conditions. This model's practical design is completed with ease of installation considerations like standard cavity T31A compatibility and manageable installation torque specifications.

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.
