The Sun Hydraulics DNCADZN948 (DNCADZN948) is a solenoid-operated, 4-way, 2-position cartridge valve characterized by its direct-acting, balanced spool design. This valve facilitates precise control in hydraulic systems by allowing for closed transitions between positions, which minimizes oil loss during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. It operates with a capacity of 8 gpm/30 L/min and can handle a maximum operating pressure of 5000 psi/350 bar. Engineered for robust performance, the DNCADZN948 requires no minimum hydraulic pressure to function and features a solenoid tube assembly rated for fatigue at 5000 psi/350 bar service. Its wet armature design means that the working fluid surrounds the armature, which is beneficial for heat dissipation but requires consideration regarding fluid selection to avoid breakdowns from prolonged heat exposure. Specifically designed EPDM seals in certain configurations make it suitable for systems using phosphate ester fluids, though these seals must not be exposed to petroleum-based substances. The valve's unique magnetic design enhances solenoid efficiency, providing high actuating force per watt expended and ensuring reliable operation. It supports various coil termination and voltage options, including models with surge protection and weatherized variants for enhanced environmental resilience. Additionally, coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either orientation on the tube. This model incorporates Sun's floating style construction which helps prevent internal parts binding due to installation torque or machining variations of the cavity/cartridge. The manual override feature requires minimal force and provides rapid response times typical at 50 ms. With its comprehensive design features tailored for demanding hydraulic applications, the DNCADZN948 offers a dependable solution for directing flow efficiently within hydraulic circuits.

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.
