The Sun Hydraulics DNDYXXN812N (DNDYXXN812N) is a solenoid-operated, 6-way, 2-position cartridge valve designed for efficient circuit selection between two separate hydraulic circuits. In its de-energized state, it connects ports P and T to the first circuit, while energizing the solenoid connects them to the second circuit. The valve is direct-acting and balanced spool type, requiring no minimum hydraulic pressure for operation. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar) service pressure. The design incorporates a wet armature, exposing the armature to working fluid and coil-generated heat, which may affect certain fluids over time. This model offers various manual override options, including no override, although manual overrides are incompatible with weatherized coils. The DNDYXXN812N boasts high efficiency due to its unique magnetic design and high spool actuating force per watt expended. It supports interchangeable coils with other Sun Series 1 solenoid products, which can be mounted in either direction and have connector options rated up to IP69K for enhanced environmental protection. The valve employs Sun's floating style construction to minimize binding risks from excessive torque or machining variations. With a capacity of 5 gpm (20 L/min), this cartridge valve has a typical response time of 50 ms and can endure a switching frequency of up to 15,000 cycles/hr. Maximum leakage at 110 SUS (24 cSt) is limited to 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). Installation requires a torque of 30-35 lbf ft (41-47 Nm), and the model weighs approximately .60 lb (.30 kg). Available seal kits include Viton options 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.
