The Sun Hydraulics DNDATTN72499 (DNDATTN72499) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct acting and balanced spool directional control. This valve operates efficiently under a maximum pressure of 5000 psi (350 bar) and does not require a minimum hydraulic pressure for activation. The solenoid tube assembly is fatigue-rated, ensuring durability and reliability in high-pressure applications. It features a wet armature design that enhances performance by allowing the working fluid to cool the armature, though care should be taken with fluids like water-glycol mixtures that can degrade under heat. The valve supports various manual override options, though these are incompatible with weatherized coils. Models with D or L control include a detent mechanism for temporary actuation, with an estimated mechanical life of about 7,000 cycles. The cartridge is compatible with EPDM seals for systems using phosphate ester fluids but should avoid petroleum-based substances to prevent seal damage. It offers numerous coil termination and voltage configurations, some including surge protection, and interchangeable coils compatible with other Sun Series 1 solenoid products. Coil connectors provide IP69K ratings for enhanced environmental protection. The valve's unique magnetic design ensures high efficiency by maximizing spool actuating force per watt expended. Its construction incorporates Sun's floating style to reduce the risk of internal binding due to installation torque variations or machining discrepancies. The DNDATTN72499 has a capacity of 10 gpm (40 L/min) and demonstrates a typical response time of 50 ms. With a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), it supports high switching frequencies up to 15,000 cycles per hour. Installation requires a torque between 30-35 lbf-ft (41-47 Nm), and the model weighs approximately .60 lb (.30 kg).

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.
