The Sun Hydraulics DNCALBN248 (DNCALBN248) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting operation with a balanced spool for reliable directional control in hydraulic systems. This model features a closed transition between positions, significantly minimizing oil loss during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. Engineered for robust performance, the DNCALBN248 can handle a maximum operating pressure of 5000 psi (350 bar) and has a rated flow capacity of 8 gpm (30 L/min), making it suitable for various demanding applications. The valve's solenoid tube assembly is fatigue rated for high-pressure service and supports reverse flow, although optimal performance in this mode is not guaranteed. It requires no minimum hydraulic pressure to operate effectively, which enhances its versatility in different system configurations. The DNCALBN248 utilizes EPDM seals specifically designed for compatibility with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as this can cause damage. Additionally, the wet armature design of the DNCALBN248 ensures that the working fluid surrounds the armature, potentially affecting fluid properties if the coil remains energized over extended periods. Various coil termination and voltage options are available to suit diverse operational requirements and environments, including options with IP69K-rated connectors for enhanced durability against harsh conditions. This model also incorporates Sun\u2019s innovative floating style construction to minimize internal parts binding due to installation variances or machining discrepancies. With interchangeable coils compatible with other Sun Series 1 solenoid products and a variety of environmental protection enhancements available, the DNCALBN248 offers flexibility and reliability for advanced hydraulic system applications.

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.
