The Sun Hydraulics DNDATTV848 (DNDATTV848) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered for high performance with a fatigue-rated solenoid tube assembly capable of handling 5000 psi (350 bar) service. It operates without the need for minimum hydraulic pressure and offers various manual override options, though manual override features are not compatible with weatherized coils. The D, L, and T control models feature a detent mechanism in the manual override intended for temporary actuation, with an estimated mechanical life of approximately 7,000 cycles. The valve utilizes a wet armature design which immerses the armature in the working fluid to manage heat generated by the coil\u2014a consideration when energized for prolonged periods. Fluids such as water-glycol mixtures may degrade under these conditions over time. The cartridge accommodates EPDM seals suitable for phosphate ester fluids but is not compatible with petroleum-based fluids. With a capacity of 10 gpm (40 L/min) and maximum operating pressure of 5000 psi (350 bar), this model supports high-efficiency operation due to its unique magnetic solenoid design. The DNDATTV848 incorporates Sun's floating style construction to minimize binding risks from excessive installation torque or machining variations. It features interchangeable coils compatible with other Sun Series 1 products, offering various termination and voltage options with surge protection capabilities. Coil connector options are rated up to IP69K, ensuring robust environmental protection. Designed for reliable performance, this valve is ideal for applications requiring frequent switching cycles\u2014up to 15,000 cycles per hour\u2014with a typical response time of 50 ms and minimal leakage at specified conditions.

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- 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.
- This cartridge has several manual override choices, including no manual override. See the CONFIGURATION section. Please note: Manual override functionality is not compatible with weatherized coils.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- Cartridges 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.
