The Sun Hydraulics DNDATSN299 (DNDATSN299) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for high-pressure applications. This valve operates without the need for minimum hydraulic pressure and offers various manual override options, although manual override is not compatible with weatherized coils. The D and L control models include a detent mechanism intended for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. The cartridge is compatible with EPDM seals for phosphate ester fluid systems but requires caution against petroleum-based fluids that may damage the seals. The valve incorporates a wet armature design where the working fluid surrounds the armature, potentially affecting performance if energized for prolonged periods due to heat exposure. Notably, water-glycol mixtures may degrade under these conditions leading to varnish formation. A variety of coil termination and voltage configurations are available to suit different needs, including options with surge protection. The high-efficiency solenoid design ensures reliable valve shifting by maximizing actuating force per watt expended. The Sun Hydraulics DNDATSN299 utilizes floating style construction to reduce internal part binding risks from excessive installation torque or machining variations. It fits into T31A cavities and supports capacities up to 10 gpm (40 L/min). It boasts a typical response time of 50 ms and can handle switching frequencies up to 15,000 cycles per hour. Additional specifications include a maximum leakage rate of 10 in\u00b3/min at 3000 psi and an installation torque requirement between 30-35 lbf-ft (41-47 Nm). The model weighs approximately .60 lb (.30 kg) and includes Viton seal kits 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.
