The Sun Hydraulics DNDYTXV212 (DNDYTXV212) is a solenoid-operated, 6-way, 2-position cartridge valve designed for efficient circuit selection between two separate hydraulic circuits. This direct-acting, balanced spool valve functions by connecting ports P and T to the first circuit in a de-energized state and shifts to connect P and T to the second circuit when energized. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure without requiring any minimum hydraulic pressure for operation. The valve\u2019s manual control assembly options include temporary actuation with detent mechanisms, offering approximately 7,000 cycles of mechanical life expectancy. The DNDYTXV212 cartridge employs a wet armature design, which allows the working fluid to cool the armature but requires attention when using fluids like water-glycol mixtures that may degrade over time due to heat exposure. This high-efficiency solenoid valve offers various coil termination and voltage configurations with optional surge protection, ensuring reliable performance across different applications. Coils are compatible with other Sun Series 1 solenoid products, providing flexibility in installation direction and environmental protection with options for weatherized coils rated up to IP69K. The valve incorporates Sun's floating style construction to minimize internal binding risks due to excessive torque or machining variations. With a capacity of 5 gpm (20 L/min), response time typically at 50 ms, and maximum leakage of 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), it is designed for robust performance with a switching frequency of up to 15,000 cycles per hour. Installation requires a torque of 30-35 lbf\u00b7ft (41-47 Nm), and it features an override force requirement of 5 lbs/1000 psi per port with an override stroke of .10 inches (2.5 mm).

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.
