The Sun Hydraulics DNDYLXV514 (DNDYLXV514) is a solenoid-operated 6-way, 2-position cartridge valve designed for selecting between two separate hydraulic circuits. In its de-energized state, the valve connects ports P and T to the first circuit, while energizing it reroutes P and T to the second circuit. This direct-acting, balanced spool valve does not require minimum hydraulic pressure for operation, making it versatile for various applications. The solenoid tube assembly is rated for fatigue at 5000 psi (350 bar), ensuring durability under high-pressure conditions. Its wet armature design allows the working fluid to cool the armature but requires consideration of fluid types as some may degrade at high temperatures over time. The DNDYLXV514 offers multiple manual override options, although these are not compatible with weatherized coils. The manual control assembly has a mechanical life expectancy of about 7,000 cycles and requires a force of 5 lbs (1000 psi) at Port 1 for actuation. The valve features interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction. Coil connector options provide ratings up to IP69K for enhanced environmental protection. The unique magnetic design of the solenoid ensures high efficiency by delivering significant spool actuating force per watt used, contributing to reliable performance in switching operations with a typical response time of 50 ms. The cartridge's construction minimizes internal binding risks due to installation torque or machining variations. With a capacity of 5 gpm (20 L/min) and a leakage rate of up to 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), this model supports frequent switching cycles up to 15,000 cycles/hr, making it suitable for demanding applications where reliability and precision are critical.

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.
