The Sun Hydraulics DNDAMYN299 (DNDAMYN299) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered with a fatigue-rated solenoid tube assembly for 5000 psi (350 bar) service, ensuring durability and reliability in high-pressure applications. It operates without requiring minimum hydraulic pressure, making it versatile for various systems. The DNDAMYN299 offers multiple manual override options; however, note that manual overrides are not compatible with weatherized coils. For models with the D or L control, the detent mechanism is intended for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. The valve features EPDM seals suitable for systems using phosphate ester fluids but are incompatible with petroleum-based fluids. Its wet armature design allows the working fluid to cool the armature, although prolonged coil energization can lead to fluid breakdown in certain mixtures like water-glycol. The solenoid's magnetic design enhances efficiency by increasing spool actuating force per watt expended. This cartridge fits the T31A cavity and belongs to Series 1, with a capacity of 10 gpm (40 L/min). It handles a maximum operating pressure of 5000 psi (350 bar) and typically responds within 50 ms. Valve leakage at maximum conditions is minimal at 10 in\u00b3/min (160 cc/min). With a switching frequency of up to 15,000 cycles/hr, it suits high-demand applications. Manual override requires a force of approximately 5 lbs/1000 psi and has a stroke of .10 inches (2.5 mm). Installation requires torque between 30-35 lbf ft (41-47 Nm), and its hex size measures .78 inches (22.2 mm). The valve weighs .60 lb (.30 kg), providing compactness without compromising performance. Seal kits are available in Viton material for both cartridge and coil components to ensure compatibility and longevity in various operating environments.

This solenoid-operated 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- 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.
- 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.
- 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.
- Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- 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.
