The Sun Hydraulics DNDYLXN628 (DNDYLXN628) 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 the solenoid shifts the connection to the second circuit. This direct-acting, balanced spool valve requires no minimum hydraulic pressure for operation, making it highly versatile in various applications. It features a fatigue-rated solenoid tube assembly suitable for service pressures up to 5000 psi (350 bar). The valve incorporates a wet armature design that allows working fluid to surround the armature, which can impact performance if energized for extended periods. Users should be cautious with fluids like water-glycol mixtures that might degrade under heat exposure. The DNDYLXN628 offers multiple manual override options; however, these are not compatible with weatherized coils. The manual control assembly has an estimated mechanical life of approximately 7,000 cycles. Coil interchangeability with other Sun Series 1 solenoid products provides flexibility in installation direction and configuration options for coil termination and voltage, including surge protection. The high-efficiency magnetic design of the solenoid ensures reliable valve shifting by maximizing spool actuating force per watt expended. With a capacity of 5 gpm (20 L/min) and a typical response time of 50 ms, this cartridge is capable of handling frequent switching operations up to 15,000 cycles per hour. The maximum leakage rate at standard conditions is measured at 5 in\u00b3/min (80 cc/min) at 3000 psi (210 bar). Its compact size and robust construction minimize internal part binding risks due to installation torque variations or machining inconsistencies. For maintenance or replacement needs, Viton seal kits are available 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.
