The Sun Hydraulics DNDATRV71299 (DNDATRV71299) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure. It operates without the need for minimum hydraulic pressure, making it suitable for various applications. The DNDATRV71299 offers multiple manual override options, although these are not compatible with weatherized coils. Models featuring the D or L control include a detent mechanism intended for temporary actuation with an estimated mechanical life of approximately 7,000 cycles. This valve incorporates EPDM seals specifically for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The wet armature design allows the working fluid to surround the armature, potentially affecting performance over long periods if exposed to high temperatures from the coil. A variety of coil termination and voltage options are available, some offering surge protection and IP69K ratings for enhanced environmental resilience. The DNDATRV71299 features Sun\u2019s floating style construction to reduce internal part binding due to installation torque or machining variations. It has a cavity size of T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The valve's response time is typically around 50 ms, and it has a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). With a switching frequency capability of up to 15,000 cycles per hour, it provides reliable performance in demanding applications. The model's hex size is .78 inches (22.2 mm), and it requires an installation torque between 30-35 lbf ft (41-47 Nm). Weighing .60 lb (.30 kg), this versatile valve offers robust functionality for various hydraulic systems.

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.
