The Sun Hydraulics DNDYDXV628 (DNDYDXV628) 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, it connects ports P and T to the first circuit, and when energized, it switches to connect P and T to the second circuit. This valve is direct-acting and does not require minimum hydraulic pressure for operation, making it versatile for various applications. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure. The valve incorporates a wet armature design, which helps manage heat dissipation effectively but requires consideration with certain fluids that may degrade at high temperatures over time. The DNDYDXV628 offers several manual override options, though these are not compatible with weatherized coils. The manual control assembly has an estimated mechanical life expectancy of around 7,000 cycles. A variety of coil termination and voltage options are available for this model, ensuring customization based on specific application needs. The unique magnetic design of the solenoid provides high efficiency by delivering significant spool actuating force per watt used. This model's construction minimizes potential binding issues due to installation torque or machining variations thanks to its floating style design. It fits into cavity T-61A and belongs to Series 1 with a capacity of up to 5 gpm (20 L/min). The valve supports a maximum operating pressure of 5000 psi (350 bar) and features a typical response time of 50 ms. With interchangeable coils across Sun Series 1 products and IP69K-rated connector options available, this valve is adaptable for demanding environments requiring robust performance.

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.
