The Sun Hydraulics DNDYMXN71299 (DNDYMXN71299) is a solenoid-operated 6-way, 2-position cartridge valve designed for efficient circuit selection between two separate hydraulic circuits. In its deenergized state, the valve connects ports P and T to the first circuit, while energizing the solenoid redirects these ports to a second circuit. This direct-acting, balanced spool valve is fatigue-rated for service up to 5000 psi (350 bar) and requires no minimum hydraulic pressure for operation, making it highly versatile in various applications. The valve features a unique wet armature design that allows working fluid to surround the armature, which can influence performance if the coil remains energized over extended periods. The DNDYMXN71299 model offers several manual override options including configurations without manual override; however, these are not compatible with weatherized coils. The manual control assembly is rated for approximately 7,000 cycles and requires an override force of 5 lbs at 1000 psi (33 N at 100 bar). This cartridge's solenoid tube has a diameter of .75 inches (19 mm), with a hex size of .78 inches (22.2 mm), and it should be installed with torque between 30 - 35 lbf ft (41 - 47 Nm). It incorporates Sun's floating style construction to minimize binding risks due to machining variations or excessive installation torque. The high-efficiency solenoid design ensures reliable valve shifting with significant spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoids and can be mounted in either direction, offering IP69K-rated connector options for enhanced environmental protection. The valve supports a capacity of up to 5 gpm (20 L/min) and has a typical response time of 50 ms with maximum leakage at specified conditions being minimal at 5 in\u00b3/min (80 cc/min).

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.
