The Sun Hydraulics DNDYTXN928 (DNDYTXN928) is a solenoid-operated 6-way, 2-position cartridge valve designed for direct-acting applications with a balanced spool configuration. It is typically used for selecting between two separate hydraulic circuits. In its de-energized state, the valve connects ports P and T to the first circuit, and when energized, it redirects flow to the second circuit. The solenoid tube assembly is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring robust performance in demanding environments. This valve does not require a minimum hydraulic pressure for operation due to its direct actuation design. The DNDYTXN928 offers various manual override options, including configurations without manual override; however, manual override functionality is incompatible with weatherized coils. It features a wet armature design that exposes the working fluid to heat generated by the coil, which could affect fluids like water-glycol mixtures over time if the coil remains energized for extended periods. The valve's high-efficiency solenoid ensures reliable shifting by providing substantial spool actuating force per watt of power consumed. This cartridge incorporates Sun's floating style construction to minimize internal binding risks due to excessive installation torque or machining variations. It supports a wide range of coil termination and voltage options, with interchangeable coils compatible with other Sun Series 1 solenoid products. Coil connector options are rated up to IP69K, providing excellent environmental protection when paired with available weatherized coils and kits. With a capacity of 5 gpm (20 L/min) and a typical response time of 50 ms, this valve can handle high-frequency switching up to 15,000 cycles per hour while maintaining minimal leakage at specified conditions. The DNDYTXN928 also includes Viton seal kits for both the cartridge and coil components, ensuring durability in various applications.

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.
