The Sun Hydraulics DNDATUV299 (DNDATUV299) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. Engineered for robust performance, the solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), ensuring reliable operation without requiring minimum hydraulic pressure. The valve offers multiple manual override options, including configurations without manual override. Notably, the manual control's detent mechanism is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. The valve's EPDM seals are suitable for systems using phosphate ester fluids but can be damaged by petroleum-based substances. Utilizing a wet armature design, this cartridge valve allows working fluid exposure to coil-generated heat, which could impact the function over time in certain fluids like water-glycol mixtures. The DNDATUV299 provides various coil termination and voltage options with surge protection capabilities. Its high-efficiency magnetic design ensures superior spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Connector options offer ratings up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or cavity machining variations. Additional specifications include a T31A cavity, Series 1 classification, a capacity of 10 gpm (40 L/min), typical response time of 50 ms, and maximum leakage at specified conditions of 10 in\u00b3/min (160 cc/min). It supports switching frequency up to 15,000 cycles/hr and requires manual override force of approximately 5 lbs/1000 psi at Port 1. The valve's compact dimensions include a .75 in solenoid tube diameter and an installation torque requirement between 30-35 lbf ft (41-47 Nm).

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.
