The Sun Hydraulics DNDATNN948 (DNDATNN948) is a solenoid-operated, 4-way, 2-position direct-acting balanced spool directional valve. Designed for high-efficiency operation, this cartridge valve is fatigue-rated for service up to 5000 psi (350 bar), ensuring robust performance in demanding applications. It features a wet armature design, where the working fluid surrounds the armature and absorbs heat generated by the coil, which can be a consideration in systems with extended coil energization periods. The valve does not require a minimum hydraulic pressure to operate and offers various manual override options, although manual overrides are not compatible with weatherized coils. The DNDATNN948 incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. It supports a capacity of 10 gpm (40 L/min) and exhibits a typical response time of 50 ms. With maximum leakage at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), it maintains efficiency during operation. The valve also supports a switching frequency of up to 15,000 cycles per hour. For systems using phosphate ester fluids, cartridges with EPDM seals are recommended as exposure to petroleum-based fluids can damage these seals. The solenoid's magnetic design delivers high actuating force per watt, enhancing reliability and efficiency in valve shifting operations. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted bidirectionally on the tube, offering flexibility in installation. Various coil termination and voltage options are available for customization needs, including those with surge protection capabilities. This model has dimensions suitable for its function: a solenoid tube diameter of .75 inches (19 mm), a hex size of .78 inches (22.2 mm), and an installation torque range of 30-35 lbf\u00b7ft (41-47 Nm). The model weighs approximately .60 lb (.30 kg).

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.
