The Sun Hydraulics DNDYTXN624 (DNDYTXN624) is a solenoid-operated, 6-way, 2-position cartridge valve designed for selecting between two separate hydraulic circuits. In its de-energized state, the valve connects ports P and T to the first circuit, while energizing it switches the connection to the second circuit. This direct-acting valve requires no minimum hydraulic pressure for operation and features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. The valve incorporates a balanced spool design and offers several manual override options, though manual override is not compatible with weatherized coils. It employs a wet armature design which allows the working fluid to cool the coil, although this may lead to degradation in certain fluids like water-glycol mixtures over time. The DNDYTXN624 showcases high efficiency with its unique magnetic solenoid design, providing reliable shifting with high spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoid products and offer various termination and voltage options, including configurations with surge protection. Additionally, coil connectors are available with ratings up to IP69K for enhanced environmental protection. This cartridge uses Sun's floating style construction to reduce internal part binding risks due to installation torque or cavity-cartridge machining variations. It fits into a T-61A cavity and has a capacity of 5 gpm (20 L/min). The typical response time is around 50 ms, with maximum leakage at 5 in\u00b3/min (80 cc/min) at 3000 psi (210 bar). The valve supports switching frequencies up to 15,000 cycles per hour and requires a manual override force of approximately 5 lbs/1000 psi at Port 1. The model weighs about .60 lb (.30 kg) and includes Viton seal kits for both the 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.
