The Sun Hydraulics DNDATLN924 (DNDATLN924) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve features a solenoid tube assembly fatigue rated for up to 5000 psi (350 bar), ensuring high durability in demanding applications. It operates without requiring minimum hydraulic pressure and offers various manual override options, although these are not compatible with weatherized coils. The manual override's detent mechanism is intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Designed with EPDM seals, this valve is suitable for systems using phosphate ester fluids but should avoid petroleum-based substances to prevent seal damage. The DNDATLN924 incorporates a wet armature design allowing the working fluid to cool the armature and coil; however, caution is advised as certain fluids may degrade under prolonged heat exposure. The solenoid\u2019s magnetic design ensures efficient operation with high actuating force per watt expended. It supports multiple coil termination and voltage options, some offering surge protection, and its coils are interchangeable within the Sun Series 1 solenoid products. Engineered with Sun's floating style construction, this valve minimizes internal binding risks due to installation torque or cavity machining variations. It has a capacity of 10 gpm (40 L/min) and can handle a maximum operating pressure of 5000 psi (350 bar). The typical response time is about 50 ms with minimal leakage at specified conditions. This model supports high switching frequency up to 15,000 cycles/hr and requires specific force and stroke for manual override operations. The cartridge fits into T31A cavities and weighs approximately .60 lb (.30 kg). For maintenance or replacement needs, Viton seal kits are available for both the cartridge and coil components.

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.
