The Sun Hydraulics DNDYTXN948 (DNDYTXN948) is a solenoid-operated 6-way, 2-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 energization redirects the flow to the second circuit. The solenoid tube assembly is robustly rated for service up to 5000 psi (350 bar), ensuring durability under high-pressure conditions. Notably, this direct-acting valve operates without requiring a minimum hydraulic pressure, making it versatile for various applications. The DNDYTXN948 features a wet armature design where the working fluid surrounds the armature, potentially affecting performance if exposed to heat from prolonged coil energization. This design consideration is crucial when using fluids like water-glycol mixtures that may degrade under such conditions. The valve offers multiple manual override options, though these are not compatible with weatherized coils. A key attribute of this valve is its high-efficiency solenoid with a unique magnetic design that provides significant spool actuating force per watt expended. This efficiency ensures reliable and effective valve shifting. The interchangeable coils can be mounted in either direction and offer various termination and voltage options, including configurations with surge protection. Additionally, coil connector options are available with ratings up to IP69K for enhanced environmental protection. The Sun Hydraulics DNDYTXN948 incorporates floating style construction to reduce the risk of internal part binding due to installation torque or machining variations in cavity/cartridge interfaces. With a capacity of 5 gpm (20 L/min) and a typical response time of 50 ms, this model is engineered for rapid operation with maximum leakage at 110 SUS (24 cSt) being just 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar).

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.
