The Sun Hydraulics DNDAMXE628 (DNDAMXE628) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service pressure, ensuring robust performance in demanding applications. It operates without the need for minimum hydraulic pressure and offers several manual override options, although these are incompatible with weatherized coils. The manual override mechanism is designed for temporary actuation with a life expectancy of approximately 7,000 cycles. Notably, cartridges with EPDM seals are intended for phosphate ester fluid systems and may be damaged by petroleum-based substances. This valve employs a wet armature design that allows the working fluid to cool the armature, although prolonged coil energization can lead to fluid breakdown in certain mixtures. A variety of coil termination and voltage options are available, enhancing versatility and providing surge protection if needed. The high-efficiency solenoid design ensures reliable valve shifting by delivering high spool actuating force per watt expended. The interchangeable coils can be mounted in either direction on the tube and offer IP69K-rated connector options for enhanced environmental protection. The DNDAMXE628 incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. It fits into T31A cavities and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The valve demonstrates rapid response times of approximately 50 ms and tolerates switching frequencies up to 15,000 cycles per hour. Maximum leakage at standard conditions is limited to 10 in\u00b3/min (160 cc/min), ensuring efficient operation across various 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.
