The Sun Hydraulics DNDYDXN714 (DNDYDXN714) is a solenoid-operated 6-way, 2-position cartridge valve designed for direct-acting, balanced spool applications. This valve is primarily utilized for selecting between two separate hydraulic circuits. In its deenergized state, it connects P and T to the first circuit, and when energized, it shifts to connect P and T to the second circuit. The solenoid tube assembly is rated for fatigue resistance at 5000 psi (350 bar), ensuring durability in high-pressure environments. Notably, this valve operates without requiring minimum hydraulic pressure due to its direct actuation design. It features various manual override options and a detent mechanism in models equipped with D or L control for temporary actuation. The mechanical life expectancy of the manual control assembly is approximately 7,000 cycles. The valve incorporates a wet armature design where the working fluid surrounds the armature, which can be crucial if the coil remains energized for extended periods as certain fluids may degrade at high temperatures. A wide range of coil termination and voltage options are available, including configurations with surge protection. The solenoid's magnetic design delivers high efficiency with substantial spool actuating force per Watt expended, ensuring reliable shifting performance. This model supports interchangeable coils with other Sun Series 1 solenoid products and can accommodate coil mounting in either direction. Coil connector options offer protection ratings up to IP69K for enhanced environmental resilience. Additionally, this valve employs Sun's floating style construction to mitigate internal part binding from excessive installation torque or machining variations in cavity/cartridge configurations. With a capacity of 5 gpm (20 L/min) and a switching frequency of up to 15,000 cycles per hour, this cartridge valve provides robust performance in demanding applications.

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.
