The Sun Hydraulics DNDATRV724N (DNDATRV724N) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to operate under a maximum pressure of 5000 psi (350 bar) and does not require minimum hydraulic pressure for activation. It includes several manual override options, although weatherized coils are incompatible with manual override functions. The detent mechanism in the D or L control models is intended for temporary use with a mechanical life expectancy of around 7,000 cycles. This valve features EPDM seals suitable for systems using phosphate ester fluids but should not be exposed to petroleum-based substances. The wet armature design allows the working fluid to surround the armature, potentially affecting functionality if the coil remains energized for extended periods, especially with water-glycol mixtures that could degrade over time. The high-efficiency solenoid design provides significant spool actuating force per watt, ensuring reliable operation. The coil options are versatile with various termination and voltage configurations available, some offering surge protection and IP69K ratings for enhanced environmental resistance. Interchangeable coils can be mounted in either direction on the tube, adding flexibility in installation. The valve incorporates Sun's floating style construction to reduce internal part binding due to excessive torque or machining variations during installation. It fits into a T-31A cavity and belongs to Series 1, with a flow capacity of up to 10 gpm (40 L/min). The typical response time is approximately 50 ms, and it supports a switching frequency of up to 15,000 cycles per hour. Installation requires a torque setting between 30-35 lbf-ft (41-47 Nm), and it 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.
