The Sun Hydraulics DNCADJN948 (DNCADJN948) 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 ensures a closed transition between positions, minimizing oil loss during shifting, crucial for maintaining efficiency in pilot control circuits. The valve is uniquely constructed to handle a maximum operating pressure of 5000 psi (350 bar), with a capacity of 8 gpm (30 L/min). It features a rapid response time of approximately 50 ms and maintains low leakage rates under high pressure. Engineered for durability and reliability, the DNCADJN948 valve incorporates Sun\u2019s floating style construction which prevents internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining. This design feature enhances the longevity and performance consistency of the valve in demanding applications. The solenoid tube assembly of this model is fatigue rated for high-pressure service up to 5000 psi, ensuring robust performance even under strenuous conditions. Moreover, the DNCADJN948 offers flexibility in terms of electrical connectivity with various coil termination and voltage options available, including models with surge protection. These coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different installation requirements. For environments requiring additional protection against elements, weatherized coils and kits are also available. This valve is particularly suited for use with systems utilizing phosphate ester fluids when configured with EPDM seals. However, it's critical to avoid exposure to petroleum-based fluids which can damage the seals. The wet armature design aids in effective heat management but may affect fluid integrity if exposed over prolonged periods. Overall, the DNCADJN948 provides reliable shifting and high spool actuating force per Watt expended due to its efficient magnetic design, making it an excellent choice for varied hydraulic applications requiring precise directional 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.
