The Sun Hydraulics DNDATSN724 (DNDATSN724) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. Built for demanding applications, this valve is fatigue rated for service up to 5000 psi (350 bar). It operates without requiring minimum hydraulic pressure, making it versatile for various hydraulic systems. The DNDATSN724 offers multiple manual override options; however, note that these are not compatible with weatherized coils. Particularly, models with D or L control have a detent mechanism intended for temporary actuation and offer a mechanical life expectancy of around 7,000 cycles. This cartridge valve utilizes EPDM seals suitable for phosphate ester fluid systems but can be damaged by petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature and absorb heat from the coil\u2014a crucial consideration if the coil remains energized for extended periods. The valve's high-efficiency solenoid provides robust spool actuation force per watt expended, ensuring reliable shifting even under challenging conditions. It accommodates various coil termination and voltage options with interchangeable coils compatible with other Sun Series 1 solenoid products. The DNDATSN724 incorporates Sun's floating style construction to prevent internal part binding due to excessive torque or machining variations in cavity/cartridge installations. It fits into a T31A cavity and boasts a capacity of 10 gpm (40 L/min) at maximum operating pressure. Designed for rapid response, it typically switches in about 50 ms while maintaining minimal leakage rates at specified conditions. With an operational switching frequency of up to 15,000 cycles per hour and manual override force requirements detailed in its specifications, this valve is engineered for performance and reliability in dynamic environments.

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.
