The Sun Hydraulics DNDAXDV928 (Material Number: DNDAXDV928) 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 capable of handling up to 5000 psi (350 bar), ensuring robust performance in demanding applications. It operates without requiring a minimum hydraulic pressure, making it versatile for various systems. The cartridge offers multiple manual override options, although not compatible with weatherized coils. Detent mechanisms in the manual override are intended for temporary use with an expected mechanical life of around 7,000 cycles. It is important to note that cartridges with EPDM seals should only be used with phosphate ester fluids to avoid damage from petroleum-based substances. The valve's wet armature design allows the working fluid to surround the armature, which can be a consideration when the coil is energized for extended periods due to potential fluid degradation at high temperatures. A range of coil termination and voltage options are available, including surge protection features. The high-efficiency solenoid design provides significant actuating force per watt, ensuring reliable valve operation. The coils are interchangeable within the Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. This cartridge incorporates Sun's floating style construction to reduce internal part binding from excessive installation torque or machining variations. With a capacity of 10 gpm (40 L/min), it boasts a typical response time of 50 ms and supports switching frequencies up to 15,000 cycles per hour. The maximum valve leakage at specified conditions is minimal at 10 in\u00b3/min (160 cc/min). Additional specifications include a cavity size of T-31A and a seal kit option with Viton material for enhanced durability.

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.
