The Sun Hydraulics DNDAXDN648 (Material Number: DNDAXDN648) is a solenoid-operated, 4-way, 2-position cartridge valve designed for high-efficiency directional control in hydraulic systems. This direct-acting, balanced spool valve requires no minimum hydraulic pressure for operation and is fatigue-rated for up to 5000 psi (350 bar) service. It features a wet armature design, which allows the working fluid to surround the armature, potentially affecting performance if the coil is energized for prolonged periods. Notably, this valve offers multiple manual override options; however, these are incompatible with weatherized coils. The detent mechanism in the manual override is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. This cartridge is specifically engineered to handle phosphate ester fluids with EPDM seals and has a capacity of 10 gpm (40 L/min). It incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. The DNDAXDN648 also provides various coil termination and voltage options with surge protection capabilities, making it adaptable to different system requirements. It can accommodate coil connector options rated up to IP69K for enhanced environmental protection. The valve boasts a response time of approximately 50 ms and supports a switching frequency of up to 15,000 cycles per hour. Its maximum leakage at 110 SUS (24 cSt) is rated at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). Installation specifications include a solenoid tube diameter of .75 inches (19 mm), a valve hex size of .78 inches (22.2 mm), and an installation torque range between 30-35 lbf ft (41-47 Nm). The model weight is approximately .60 lb (.30 kg), and it uses Viton seal kits for both cartridge and coil 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.
