The Sun Hydraulics DNCADWV724N (DNCADWV724N) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting, which is essential in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank outlet; however, it supports reverse flow under specific conditions albeit with variable performance. Rated for up to 5000 psi (350 bar) service, the solenoid tube assembly of this valve is fatigue-rated, ensuring durability and long-term performance under high-pressure conditions. It operates without requiring a minimum hydraulic pressure, making it versatile for various applications. The DNCADWV724N employs EPDM seals suitable for phosphate ester fluids but must avoid exposure to petroleum-based substances to prevent seal damage. A unique feature of this model is its wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil remains energized for extended periods as certain fluids may degrade at higher temperatures. Moreover, a variety of coil termination and voltage options are available to suit different operational needs and environments. The solenoid's magnetic design enhances efficiency by maximizing spool actuating force per watt expended, which contributes to reliable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, connector options for coils provide ratings up to IP69K for enhanced environmental protection. Incorporating Sun's floating style construction minimizes internal parts binding that could arise from excessive installation torque or cavity/cartridge machining variations. This construction detail ensures consistent operation and ease of maintenance across various industrial applications where precise fluid control is critical.

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.
