The Sun Hydraulics DNDYDXV298 (DNDYDXV298) is a solenoid-operated, six-way, two-position cartridge valve designed for efficient circuit selection between two separate hydraulic circuits. In its de-energized state, this valve connects ports P and T to the first circuit, while energizing the solenoid shifts the connection to the second circuit. Featuring a direct-acting, balanced spool design, this valve operates without requiring minimum hydraulic pressure and is rated for fatigue at 5000 psi (350 bar). The DNDYDXV298 includes options for manual override with detent mechanisms in models equipped with D or L controls, offering approximately 7,000 mechanical cycles. The wet armature design enhances durability by exposing the armature to working fluid and heat generated by the coil; however, users should be cautious of potential varnish formation in certain fluids like water-glycol mixtures over extended periods of coil energization. This model incorporates a high-efficiency solenoid with unique magnetic design for reliable spool actuation and offers interchangeable coils compatible with other Sun Series 1 solenoid products. Coil connector options provide protection ratings up to IP69K for enhanced environmental resilience. The cartridge utilizes Sun's floating style construction to mitigate internal binding risks due to installation torque or machining variations. With a capacity of 5 gpm (20 L/min), typical response time of 50 ms, and a switching frequency of up to 15,000 cycles per hour, this valve ensures rapid and consistent performance in demanding applications. The installation requires a T-61A cavity with specified torque settings between 30-35 lbf ft (41-47 Nm). Seal kits are available in Viton material for both cartridge and coil components.

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.
