The Sun Hydraulics DNDYTXV812 (DNDYTXV812) is a solenoid-operated, 6-way, 2-position cartridge valve designed for efficient circuit selection between two separate hydraulic paths. In its de-energized state, it 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 is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring robust performance without requiring a minimum hydraulic pressure for operation. The valve features a wet armature design that immerses the armature in working fluid, which can influence performance if the coil remains energized over extended periods. A variety of manual override options are available; however, these are not compatible with weatherized coils. The DNDYTXV812 model integrates Sun's unique floating style construction to reduce internal binding risks due to torque or machining variations. It supports a maximum flow capacity of 5 gpm (20 L/min) and offers a typical response time of 50 ms. The valve's leakage rate is minimal at 5 in\u00b3/min (80 cc/min) under specified conditions. With coil interchangeability across Sun Series 1 solenoid products and IP69K-rated connector options, it provides flexible installation and environmental protection solutions. The valve also includes various coil termination and voltage configurations with optional surge protection. Additionally, this cartridge benefits from high-efficiency solenoid magnetic design for reliable shifting and features a mechanical life expectancy of approximately 7,000 cycles for models equipped with specific manual controls. Installation requires a torque range of 30-35 lbf ft (41-47 Nm), and it fits into T61A cavities with a hex size of .78 in (22.2 mm). The model weighs .60 lb (.30 kg) and comes with Viton seal kits for both 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.
