The Sun Hydraulics DNDYDXV71299 (DNDYDXV71299) 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, the valve connects ports P and T to the first circuit, while energizing it switches the connection to the second circuit. This direct-acting, balanced spool valve operates without requiring any minimum hydraulic pressure, making it versatile for various applications. It features a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability and reliability under high-pressure conditions. The valve's mechanical components, such as the manual override with detent mechanisms available in D or L control models, are engineered for temporary actuation with a life expectancy of approximately 7,000 cycles. The cartridge employs a wet armature design that exposes working fluid to coil-generated heat, which is an important consideration when using fluids like water-glycol mixtures that can degrade at elevated temperatures. The solenoid's magnetic design offers high efficiency by maximizing spool actuating force per watt expended. With interchangeable coils compatible with other Sun Series 1 products and various termination and voltage options available\u2014including those with surge protection\u2014the valve can be configured to meet specific operational needs. Its construction incorporates Sun's floating style to reduce internal binding risks due to installation torque or machining variations. For environmental resilience, coil connector options are available with ratings up to IP69K, and additional weatherized coils and kits can provide comprehensive protection. The valve supports a capacity of up to 5 gpm (20 L/min) and features quick response times of around 50 milliseconds with minimal leakage rates under specified conditions. The installation requires a torque setting between 30-35 lbf ft (41-47 Nm), ensuring secure fitting in its designated cavity T61A within Series 1 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.
