The Sun Hydraulics DNDAMUV248 (DNDAMUV248) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. This valve features a solenoid tube assembly that is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability and reliability in high-pressure applications. Its direct actuation design requires no minimum hydraulic pressure, making it versatile for various hydraulic systems. The DNDAMUV248 offers several manual override options, although manual override functionality is not compatible with weatherized coils. The manual control assembly, available in D or L control configurations, has a mechanical life expectancy of approximately 7,000 cycles and is intended for temporary actuation. This cartridge valve is suitable for use with phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids will damage these seals. It incorporates a wet armature design, where the working fluid surrounds the armature and absorbs heat from the coil. This feature necessitates caution if the coil is energized for extended periods, as certain fluids can degrade over time at elevated temperatures. The valve supports a wide range of coil termination and voltage options, including those with surge protection. Its high-efficiency magnetic solenoid design provides significant spool actuating force per watt expended, ensuring reliable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options offer ratings up to IP69K for enhanced environmental protection. Additional specifications include a maximum capacity of 10 gpm (40 L/min), typical response time of 50 ms, and maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The cartridge's floating style construction minimizes internal part binding due to installation torque or machining variations.

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.
