The Sun Hydraulics DNDAMXV948 (DNDAMXV948) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring reliable performance under high-pressure conditions. This valve operates independently of hydraulic pressure, making it versatile for various applications. It offers several manual override options, although these are not compatible with weatherized coils. Models with D or L control include a detent mechanism in the manual override for temporary actuation, with an approximate mechanical life expectancy of 7,000 cycles. The cartridge is suitable for systems using phosphate ester fluids when equipped with EPDM seals but should avoid petroleum-based fluids to prevent seal damage. The wet armature design allows the working fluid to cool the armature, though prolonged coil energization may affect fluid stability, particularly in water-glycol mixtures. A range of coil termination and voltage options are available to suit different needs, including surge protection capabilities. The solenoid's unique magnetic design enhances efficiency by providing high spool actuating force per watt expended, ensuring consistent valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This model incorporates Sun's floating style construction to reduce the risk of internal binding due to installation torque or machining variations. Key specifications include a cavity size of T-31A, a capacity of 10 gpm (40 L/min), response time typically around 50 ms, and a maximum leakage rate at 110 SUS (24 cSt) of 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar). The valve is designed for easy installation with a hex size of .78 inches (22.2 mm) and an installation torque between 30-35 lbf-ft (41-47 Nm).

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.
