The Sun Hydraulics DNDAMYE298 (DNDAMYE298) is a solenoid-operated 4-way, 2-position cartridge that functions as a direct-acting, balanced spool directional valve. Designed for high-efficiency operation, this valve features a solenoid tube assembly with a fatigue rating suitable for 5000 psi (350 bar) service. Notably, it requires no minimum hydraulic pressure to operate. It offers various manual override options, although compatibility with weatherized coils is limited. The D and L controls provide temporary actuation through a detent mechanism with an approximate mechanical life of 7,000 cycles. For systems utilizing phosphate ester fluids, EPDM seals are recommended; however, they are not compatible with petroleum-based substances. The valve's wet armature design allows the working fluid to cool the armature while being exposed to coil-generated heat\u2014important in applications where the coil remains energized for extended periods. This design consideration is crucial when using fluids like water-glycol mixtures that may degrade under heat exposure. The solenoid's magnetic design ensures high efficiency by providing significant spool actuating force relative to power consumption, ensuring reliable shifting of the valve. This model supports various coil termination and voltage options and includes surge protection capabilities. It incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations in cavity/cartridge interfaces. The DNDAMYE298 fits into cavity T-31A and belongs to Series 1, offering a capacity of 10 gpm (40 L/min) with a maximum operating pressure of 5000 psi (350 bar). The typical response time is approximately 50 milliseconds, and it can handle switching frequencies up to 15,000 cycles per hour. For manual override operations, it requires a force of about 5 lbs/1000 psi at Port 1 and has an override stroke of .10 inches (2.5 mm).

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.
