The Sun Hydraulics DNDATNV748 (DNDATNV748) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve is fatigue rated for service up to 5000 psi (350 bar) and does not require any minimum hydraulic pressure for operation, making it versatile for various hydraulic systems. It features multiple manual override options, although manual override functionality is incompatible with weatherized coils. The detent mechanism in models with D or L control is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. The cartridge's wet armature design allows the working fluid to surround the armature, which is exposed to coil-generated heat\u2014an important consideration when using fluids like water-glycol mixtures that can degrade at high temperatures. The valve offers various coil termination and voltage options with or without surge protection and includes interchangeable coils compatible with other Sun Series 1 solenoid products. Coil connector options are available with ratings up to IP69K for enhanced environmental protection. The unique magnetic design of the solenoid ensures high efficiency and reliable valve shifting by providing high spool actuating force per watt expended. The floating style construction minimizes binding risks due to installation torque or machining variations. With a capacity of 10 gpm (40 L/min), a typical response time of 50 ms, and a switching frequency of up to 15,000 cycles per hour, this valve delivers efficient performance in demanding applications. It requires a manual override force of 5 lbs/1000 psi at Port 1 and has a manual override stroke of .10 inches (2.5 mm). The valve's installation torque ranges from 30 to 35 lbf ft (41 to 47 Nm), ensuring secure fitting within its T31A cavity.

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.
