The Sun Hydraulics DNCADBN228 (DNCADBN228) 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 is notable for its closed transition between positions, minimizing oil loss during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. The valve is versatile with a capacity based on port 3 as the inlet and port 1 as the tank, although it supports reverse flow under certain conditions. Engineered to operate without minimum hydraulic pressure, the DNCADBN228 ensures reliable performance across a range of applications. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for rigorous industrial use. The wet armature design of the valve means that the working fluid surrounds the armature which can be significant when the coil is energized continuously, as heat generated may affect fluid integrity over time. This model incorporates Sun\u2019s floating style construction which helps prevent internal parts binding due to installation torque or cavity/cartridge machining variations. It supports a variety of coil termination and voltage options, including models with surge protection and environmental shielding options rated up to IP69K for enhanced durability against harsh conditions. With an impressive maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 8 gpm (30 L/min), the DNCADBN228 is equipped to handle demanding tasks efficiently. Its quick response time of approximately 50 ms and switching frequency up to 15000 cycles per hour make it an excellent choice for systems requiring fast and frequent operations. Additional features like interchangeable coils with other Sun Series 1 products and various manual override capabilities further enhance its adaptability and ease of use in complex hydraulic setups.

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.
