The Sun Hydraulics DNDYXXN812 (DNDYXXN812) is a solenoid-operated 6-way, 2-position cartridge valve designed for directing hydraulic flow between two separate circuits. 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 engineered for high performance without requiring a minimum hydraulic pressure for operation. It boasts a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar), ensuring durability in demanding applications. The valve features a wet armature design that allows the working fluid to surround the armature, which can be advantageous in dissipating heat generated by prolonged coil energization. However, users should be aware that certain fluids may degrade over time under these conditions. The DNDYXXN812 offers multiple manual override options, though manual override functionality is not compatible with weatherized coils. The high-efficiency solenoid design provides significant spool actuating force per watt, promoting reliable valve shifting. The cartridge incorporates Sun's floating style construction to reduce internal binding risks due to installation torque or machining variations. With a capacity of 5 gpm (20 L/min) and maximum leakage of 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), this valve ensures efficient operation. Interchangeable coils with various termination and voltage options are available, including models with surge protection and IP69K-rated connector options. The DNDYXXN812 supports a switching frequency of up to 15,000 cycles per hour and has a typical response time of 50 ms. Installation requires a torque range of 30-35 lbf ft (41-47 Nm), and the model weighs approximately 0.60 lb (0.30 kg).

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.
