The Sun Hydraulics DNDAMZN748 (DNDAMZN748) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Engineered to handle fatigue-rated pressures up to 5000 psi (350 bar), this valve operates without requiring minimum hydraulic pressure. It features multiple manual override options, including models with temporary detent mechanisms for actuation, and offers a mechanical life expectancy of approximately 7,000 cycles. The cartridge is compatible with EPDM seals for systems using phosphate ester fluids, though exposure to petroleum-based substances can damage these seals. Utilizing a wet armature design, the valve's working fluid surrounds the armature and interacts with coil-generated heat, which may affect performance over extended energization periods\u2014especially in water-glycol mixtures that could degrade into varnishes. With an efficient magnetic solenoid design, it provides high spool actuating force per watt, ensuring reliable shifting. The interchangeable coils fit other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. Coil connector options support ratings up to IP69K for enhanced environmental protection. The Sun floating style construction minimizes internal part binding risks due to excessive installation torque or machining variations in cavities/cartridges. The valve fits T31A cavities and supports flow capacities up to 10 gpm (40 L/min). It is designed with a typical response time of 50 ms and allows maximum leakage at 110 SUS of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The valve can handle switching frequencies up to 15,000 cycles per hour and requires a manual override force of about 5 lbs/1000 psi at Port 1 (33 N/100 bar). Additional features include various coil termination and voltage options available with or without surge protection.

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.
