The Sun Hydraulics DNDYDXN (DNDYDXN) 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, and when energized, it switches them to the second circuit. This direct-acting valve does not require a minimum hydraulic pressure for operation and features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service. The valve incorporates a balanced spool design with several manual override options, though manual overrides are incompatible with weatherized coils. It offers high efficiency due to its unique magnetic design that provides substantial spool actuating force per watt expended. The DNDYDXN utilizes a wet armature design where the working fluid surrounds the armature, which can influence performance if the coil remains energized for extended periods. The cartridge supports various coil termination and voltage options with surge protection available. Coils can be mounted in either direction and are interchangeable with other Sun Series 1 solenoid products. Connector options offer protection ratings up to IP69K. The valve's construction minimizes internal binding risks due to installation torque or cavity-cartridge machining variations by incorporating Sun's floating style design. It fits into a T-61A cavity and has a capacity of 5 gpm (20 L/min), with maximum operating pressure at 5000 psi (350 bar). Typical response time is around 50 milliseconds, and it can handle switching frequencies up to 15,000 cycles per hour. The manual override requires approximately 5 lbs of force per 1000 psi at Port 1, with an override stroke of .10 inches (2.5 mm). The valve hex size is .78 inches (22.2 mm), requiring installation torque between 30-35 lbf-ft (41-47 Nm). The model weighs .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.
