The Sun Hydraulics DNCADTN624N (DNCADTN624N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for efficient control in hydraulic systems. It features a direct-acting, balanced spool with closed transition between positions, minimizing oil loss during shifting which is crucial in pilot control circuits. This valve is particularly noted for its capability to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 8 gpm (30 L/min), making it suitable for various demanding applications. The DNCADTN624N operates without the need for minimum hydraulic pressure, enhancing its versatility across different system conditions. It incorporates EPDM seals configured specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The valve's wet armature design allows the working fluid to surround the armature, which could be a consideration if the coil remains energized over extended periods due to potential breakdowns in certain fluid types like water-glycol mixtures. For adaptability in various environments, the DNCADTN624N offers an array of coil termination and voltage options, including versions with surge protection. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The solenoid\u2019s design ensures high efficiency and effective spool actuating force per Watt expended. Additionally, this model employs Sun's floating style construction which minimizes internal parts binding that might occur due to excessive installation torque or variations in cavity/cartridge machining. With features like manual override capabilities and response times typically around 50 ms, this valve ensures reliable performance and control precision in hydraulic systems.

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.
