The Sun Hydraulics DNDYDXN812N (DNDYDXN812N) is a solenoid-operated 6-way, 2-position cartridge valve designed for selecting between two separate circuits. In its de-energized state, it connects P and T to the first circuit, and when energized, it connects P and T to the second circuit. This valve is direct-acting and features a balanced spool design, requiring no minimum hydraulic pressure for operation. It is fatigue rated for service up to 5000 psi (350 bar), ensuring robust performance in demanding applications. The DNDYDXN812N incorporates a wet armature design, allowing the working fluid to surround the armature and absorb heat generated by the coil. This feature can impact long-term performance with certain fluids like water-glycol mixtures that may degrade at high temperatures. The valve offers a variety of manual override options, including models with no manual override. However, it's important to note that manual override functionality is not compatible with weatherized coils. This valve supports a wide range of coil termination and voltage options, some of which include surge protection. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt expended, contributing to reliable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additional features include a floating style construction that minimizes internal part binding due to installation torque or machining variations in cavity/cartridge interfaces. The valve has a capacity of 5 gpm (20 L/min) and maintains maximum operating pressure up to 5000 psi (350 bar). It exhibits typical response times of approximately 50 ms and allows for switching frequencies as high as 15,000 cycles per hour. The seal kit for this cartridge uses Viton material for enhanced durability under various conditions.

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.
