The Sun Hydraulics DNDYTXN299 (DNDYTXN299) is a solenoid-operated 6-way, 2-position cartridge valve designed for selecting between two separate circuits. In its de-energized state, it connects ports P and T to the first circuit, and when energized, it redirects them to the second circuit. The valve is direct-acting with a balanced spool design, eliminating the need for minimum hydraulic pressure for operation. It features a solenoid tube assembly that is fatigue-rated for service pressures up to 5000 psi (350 bar). The valve offers multiple manual override options, although these are not compatible with weatherized coils. Its wet armature design means that working fluid surrounds the armature, which can be affected by heat generated during prolonged coil energization. This design uses a high-efficiency solenoid that provides substantial spool actuating force per watt expended, ensuring reliable shifting. The DNDYTXN299 incorporates Sun's floating style construction to minimize potential binding of internal parts due to excessive torque or machining variations in the cavity/cartridge interface. It fits into a T-61A cavity and belongs to Series 1 with a capacity of 5 gpm (20 L/min). The valve has a typical response time of 50 ms and can handle switching frequencies up to 15,000 cycles per hour. Maximum valve leakage at 110 SUS (24 cSt) is rated at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). Manual override requires a force of approximately 5 lbs/1000 psi on Port 1, with a stroke length of .10 inches (2.5 mm). The solenoid tube diameter measures .75 inches (19 mm), and installation torque ranges from 30 to 35 lbf-ft (41 to 47 Nm). The model weighs .60 lb (.30 kg) and uses 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.
