The Sun Hydraulics DNDYXXN72499 (DNDYXXN72499) is a solenoid-operated 6-way, 2-position cartridge valve designed for direct-acting, balanced spool applications. This valve is primarily used to alternate between two distinct hydraulic circuits. In its de-energized state, it connects ports P and T to the first circuit, and when energized, it switches to the second circuit. The solenoid tube assembly is engineered for high durability, rated for 5000 psi (350 bar), ensuring reliable service in demanding conditions. Importantly, this valve does not require a minimum hydraulic pressure for operation and features a manual override option with various configurations available. The DNDYXXN72499 utilizes a wet armature design that allows the working fluid to cool the armature by surrounding it, which can be crucial in applications where the coil remains energized for extended periods. However, users should note that certain fluids like water-glycol mixtures may degrade at these temperatures over time. The solenoid's magnetic design delivers high efficiency by maximizing spool actuating force per watt consumed, resulting in dependable valve shifting. This model offers versatility with a wide range of coil termination and voltage options available, including those with surge protection. Coils are interchangeable within Sun Series 1 products and can be mounted bi-directionally on the tube. The valve incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations in cavity/cartridge. With a capacity of 5 gpm (20 L/min) and a maximum operating pressure of 5000 psi (350 bar), this cartridge is built for robust performance. It also features an impressive switching frequency of up to 15,000 cycles per hour and has been designed with user-friendly maintenance in mind through easy-to-access seal kits.

This solenoid-operated 6-way, 2-position cartridge is a direct-acting, balanced spool valve. The typical use for this valve is to select between two separate circuits. The de-energized condition connects P and T to the first circuit and when energized connects P and T to the second circuit.
- 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.
- 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.
- 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.
- 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.
