The Sun Hydraulics DNDATYN948 (DNDATYN948) is a solenoid-operated 4-way, 2-position cartridge valve designed for high efficiency and reliability in hydraulic systems. This direct-acting, balanced spool directional valve features a solenoid tube assembly fatigue rated for up to 5000 psi (350 bar) service, ensuring robust performance without requiring minimum hydraulic pressure for operation. The cartridge offers several manual override options, though these are not compatible with weatherized coils. Notably, models with D or L control include a detent mechanism intended for temporary actuation, with a mechanical life expectancy of about 7,000 cycles. The valve is equipped with EPDM seals suitable for phosphate ester fluids but should not be exposed to petroleum-based substances. Its wet armature design allows working fluid to surround the armature, which can influence performance if the coil is energized for extended periods. The solenoid's unique magnetic design enhances efficiency by delivering high spool actuating force per watt expended. This leads to reliable valve shifting and ensures that coils are interchangeable with other Sun Series 1 solenoid products. With a capacity of 10 gpm (40 L/min) and maximum operating pressure of 5000 psi (350 bar), the DNDATYN948 accommodates a wide range of coil termination and voltage options. It incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. The valve's switching frequency reaches up to 15,000 cycles per hour and features low leakage rates at specified conditions. The product is compact with a model weight of .60 lb (.30 kg), making it suitable for diverse applications requiring precise fluid control in challenging environments.

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.
