The Sun Hydraulics DNDATXV748 (DNDATXV748) is a solenoid-operated, 4-way, 2-position cartridge valve designed for efficient and reliable directional control in hydraulic systems. This direct-acting, balanced spool valve requires no minimum hydraulic pressure for operation and features a fatigue-rated solenoid tube assembly suitable for service up to 5000 psi (350 bar). The DNDATXV748 offers several manual override options, though it's important to note that these are not compatible with weatherized coils. The manual override's detent mechanism is intended for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. This valve incorporates a wet armature design where the working fluid surrounds the armature, which can affect performance if the coil is energized for extended periods. It supports various coil termination and voltage options, some with surge protection. The high-efficiency solenoid design ensures strong spool actuating force per Watt expended, promoting 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 protection ratings up to IP69K. The DNDATXV748 uses Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. It fits into cavity T-31A and supports a flow capacity of up to 10 gpm (40 L/min). With a typical response time of 50 ms and switching frequency up to 15,000 cycles/hr, this valve delivers quick and efficient operation. Maximum leakage at 110 SUS (24 cSt) is limited to 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). This model weighs approximately .60 lb (.30 kg) and comes with Viton seal kits available for both cartridge and coil components.

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.
