The Sun Hydraulics DNDYXXN648 (DNDYXXN648) is a solenoid-operated, 6-way, 2-position cartridge valve designed for selecting between two separate hydraulic circuits. In its de-energized state, it connects ports P and T to the first circuit, while energizing the solenoid switches the connection to the second circuit. This direct-acting valve does not require a minimum hydraulic pressure for operation and is fatigue rated for up to 5000 psi (350 bar). It features a wet armature design, which allows the working fluid to surround the armature, potentially affecting fluid stability if energized for extended periods. The valve supports various manual override options, including configurations with temporary actuation detent mechanisms. However, manual override functionality is not compatible with weatherized coils. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt of power used, ensuring reliable operation across its lifespan of approximately 7,000 cycles for certain manual control assemblies. The cartridge incorporates Sun's floating style construction to minimize binding risks due to installation torque or machining variations. It fits into cavity T-61A and belongs to Series 1 with a flow capacity of 5 gpm (20 L/min). Response time averages at 50 ms with maximum leakage at 5 in\u00b3/min (80 cc/min) at 3000 psi (210 bar). The valve can handle switching frequencies up to 15,000 cycles per hour and requires about 5 lbs of force per 1000 psi for manual override operation. It has a hex size of .78 inches (22.2 mm), an installation torque range of 30-35 lbf-ft (41-47 Nm), and weighs approximately .60 lb (.30 kg). Various coil termination and voltage options are available, offering IP69K ratings for enhanced environmental protection.

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.
