The Sun Hydraulics DNCADBN628 (DNCADBN628) 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, which significantly minimizes oil loss during shifting\u2014a crucial factor in maintaining efficiency in pilot control circuits. The valve's design ensures reliable operation with a capacity based on using port 3 as the inlet and port 1 as the tank. Constructed to handle rigorous use, the DNCADBN628's solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), making it suitable for high-pressure applications. It operates without requiring a minimum hydraulic pressure, offering flexibility across various hydraulic systems. The unit is equipped with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. The DNCADBN628 benefits from Sun Hydraulics' innovative wet armature design where the working fluid surrounds the armature. This setup can influence fluid integrity if subjected to prolonged heat exposure from an energized coil. The valve supports a variety of coil termination and voltage options and offers interchangeable coils compatible with other Sun Series 1 solenoid products. With its robust magnetic design, the DNCADBN628 achieves high efficiency and effective spool actuating force per Watt expended, ensuring dependable valve shifting. Additional features include IP69K-rated coil connector options for enhanced environmental protection and Sun's floating style construction which reduces internal part binding risks due to installation torque or machining variations. This model also boasts quick response times (approximately 50 ms), supports up to 15000 switching cycles per hour, and allows manual override with minimal force requirement. Its compact size includes a .75 inch solenoid tube diameter and weighs just .60 lbs., making it an optimal choice for space-constrained installations requiring precise fluid control.

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.
