The Sun Hydraulics DNDYTXN912 (DNDYTXN912) is a solenoid-operated, 6-way, 2-position cartridge valve designed for efficient hydraulic circuit selection. This direct-acting, balanced spool valve is engineered to switch between two separate circuits: in its de-energized state, it connects ports P and T to the first circuit, while energizing the solenoid redirects these connections to the second circuit. The valve's solenoid tube assembly is fatigue-rated for high-pressure service up to 5000 psi (350 bar), ensuring reliability under demanding conditions. Notably, this valve does not require a minimum hydraulic pressure for operation, enhancing its versatility in various applications. The DNDYTXN912 features a wet armature design that allows working fluid to surround the armature, which can impact performance if the coil remains energized for prolonged periods. The cartridge offers several manual override options and includes configurations without manual overrides; however, manual override functions are incompatible with weatherized coils. The high-efficiency solenoid design provides significant spool actuating force per watt expended, promoting reliable valve shifting. This model accommodates a variety of coil termination and voltage options with available surge protection and interchangeable coils compatible with other Sun Series 1 products. Coil connector options are rated up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction to minimize potential internal part binding due to excessive installation torque or machining variations. With a capacity of 5 gpm (20 L/min) and typical response time of 50 ms, this cartridge is suitable for applications requiring rapid switching frequencies up to 15000 cycles per hour. It also features Viton seal kits for both cartridge and coil components, ensuring robust sealing performance in demanding environments.

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.
