The Sun Hydraulics DNDYTXN824 (DNDYTXN824) is a solenoid-operated, 6-way, 2-position cartridge valve designed for direct-acting and balanced spool applications. It is typically used to switch between two separate hydraulic circuits. In its de-energized state, it connects ports P and T to the first circuit, while in the energized state, it connects them to the second circuit. The valve's solenoid tube assembly is fatigue-rated for service pressures up to 5000 psi (350 bar), making it highly durable for demanding applications. This model does not require a minimum hydraulic pressure for operation, allowing flexibility in various system designs. It features multiple manual override options that are not compatible with weatherized coils; these include detent mechanisms with a mechanical life expectancy of approximately 7,000 cycles. The valve's wet armature design allows the working fluid to surround the armature, which can be affected by coil heat if energized for extended periods\u2014potentially impacting fluid stability over time. The solenoid's magnetic design ensures high efficiency and reliable shifting due to high spool actuating force per watt expended. Compatible with other Sun Series 1 solenoid products, its coils can be mounted in either direction and offer IP69K-rated connector options for enhanced environmental protection. The valve incorporates Sun's floating style construction to reduce internal part binding from excessive installation torque or machining variations. With a capacity of 5 gpm (20 L/min), typical response time of 50 ms, and maximum leakage of 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), this cartridge is ideal for high-frequency switching up to 15,000 cycles per hour. Additional options include various coil termination and voltage configurations with surge protection capabilities.

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.
