The Sun Hydraulics DNDYTXN298 (DNDYTXN298) is a solenoid-operated 6-way, 2-position cartridge valve designed for selecting between two separate 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. This direct-acting valve does not require minimum hydraulic pressure for operation and is fatigue-rated for service up to 5000 psi (350 bar). It features a wet armature design where the working fluid surrounds the armature, which can be influenced by long periods of coil energization. The solenoid's magnetic design ensures high efficiency with significant spool actuating force per watt expended, resulting in reliable valve shifting. It offers various coil termination and voltage options, some with surge protection, and interchangeable coils compatible with other Sun Series 1 solenoid products. The valve allows for several manual override choices and has a mechanical life expectancy of approximately 7,000 cycles for models equipped with D or L controls. This cartridge uses Sun's floating style construction to minimize internal binding due to excessive installation torque or cavity machining variations. With a capacity of 5 gpm (20 L/min) and a maximum leakage rate of 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), this valve is suitable for applications requiring high switching frequency up to 15,000 cycles per hour. Additional features include coil connector options rated up to IP69K for enhanced environmental protection, making it versatile for demanding applications requiring robust performance under varying conditions.

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.
