The Sun Hydraulics DNDATHV524 (DNDATHV524) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve operates efficiently without requiring a minimum hydraulic pressure and is rated for a fatigue service pressure of up to 5000 psi (350 bar). It features a variety of manual override options, although manual overrides are not compatible with weatherized coils. The valve's design incorporates a wet armature system, which may affect fluid stability over prolonged coil energization periods, particularly with water-glycol mixtures. With its high-efficiency solenoid design, the valve ensures reliable shifting by maximizing spool actuating force per Watt. The DNDATHV524 supports multiple coil termination and voltage configurations, including options with surge protection and IP69K-rated connectors for enhanced environmental resilience. The cartridge employs Sun's floating style construction to reduce the risk of internal binding from installation torque or machining discrepancies. It fits into the T-31A cavity and has a capacity of 10 gpm (40 L/min). Additional specifications include a typical response time of 50 ms, maximum leakage at 110 SUS (24 cSt) of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), and a switching frequency capability of up to 15,000 cycles per hour. The manual override requires an actuation force of approximately 5 lbs/1000 psi (33 N/100 bar) at Port 1 with a stroke length of .10 inches (2.5 mm). The solenoid tube diameter is .75 inches (19 mm), while the valve hex size measures .78 inches (22.2 mm), necessitating an installation torque between 30-35 lbf ft (41-47 Nm). Weighing approximately .60 lb (.30 kg), it is available with Viton seal kits for both cartridge and coil applications.

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.
