The Sun Hydraulics DNDATHN924 (DNDATHN924) 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 applications with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure. It operates without the need for minimum hydraulic pressure and features various manual override options, although the manual override is not compatible with weatherized coils. The D and L control models include a detent mechanism intended for temporary actuation, with an estimated mechanical life expectancy of approximately 7,000 cycles. The valve incorporates EPDM seals suitable for systems utilizing phosphate ester fluids but should not be exposed to petroleum-based substances to avoid seal damage. Its wet armature design ensures that the working fluid surrounds the armature, which can impact functionality if the coil is energized for extended periods due to heat exposure. A variety of coil termination and voltage configurations are available, enhancing versatility and efficiency. With its high-efficiency magnetic solenoid design, this valve provides substantial spool actuating force per watt expended, ensuring reliable shifting performance. Its interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The valve offers IP69K-rated coil connector options and additional weatherized kits for enhanced environmental protection. Constructed with Sun's floating style design, it minimizes internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge interfaces. This model supports a flow capacity of 10 gpm (40 L/min) and allows a maximum operating pressure of 5000 psi (350 bar), making it suitable for various demanding hydraulic applications.

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.
