The Sun Hydraulics DNDATDN298 (DNDATDN298) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve is fatigue-rated for 5000 psi (350 bar) service and operates efficiently without requiring any minimum hydraulic pressure. It features multiple manual override options, including models with temporary actuation detent mechanisms, though these are not compatible with weatherized coils. The valve is suitable for use in systems utilizing phosphate ester fluids when equipped with EPDM seals, which should not be exposed to petroleum-based substances. Its wet armature design allows fluid to surround the armature, which may affect performance if the coil remains energized for extended periods due to heat exposure. The solenoid's magnetic design ensures high efficiency and reliable operation by maximizing spool actuating force per watt. The valve supports a variety of coil termination and voltage options, with some offering surge protection and IP69K ratings for enhanced environmental resilience. It incorporates Sun's floating style construction to prevent internal binding from installation torque or machining variations. The DNDATDN298 fits into a T-31A cavity and belongs to Series 1 with a capacity of 10 gpm (40 L/min). It can handle a maximum operating pressure of 5000 psi (350 bar) with typical response times of around 50 ms. The valve demonstrates minimal leakage at high viscosity levels and can operate at switching frequencies up to 15,000 cycles per hour. Manual override requires approximately 5 lbs/1000 psi force with a stroke length of .10 inches (2.5 mm). The solenoid tube diameter is .75 inches (19 mm), while the valve hex size measures .78 inches (22.2 mm). Installation torque ranges between 30-35 lbf ft (41-47 Nm), and the model weighs approximately .60 lb (.30 kg). Viton seal kits are available for both cartridge and coil components, ensuring reliable sealing performance under various 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.
