The Sun Hydraulics DNDAMZN71299 (DNDAMZN71299) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to handle high-pressure applications with a fatigue rating for 5000 psi (350 bar) service. It operates without requiring a minimum hydraulic pressure, making it versatile for various systems. The cartridge offers multiple manual override options, although these are not compatible with weatherized coils. Models with D or L control have a detent mechanism intended for temporary actuation and feature a mechanical life expectancy of approximately 7,000 cycles. The valve incorporates EPDM seals suitable for phosphate ester fluid systems; however, exposure to petroleum-based substances can damage these seals. Its wet armature design exposes the armature to working fluid and heat from the coil, which can affect performance if energized over long durations. This issue is particularly relevant when using water-glycol mixtures that may degrade at high temperatures. The solenoid's magnetic design ensures high efficiency by maximizing spool actuating force per watt of power used, facilitating reliable valve shifting. Coils are interchangeable with other Sun Series 1 products and can be mounted in either direction on the tube. Available coil connector options provide environmental protection ratings up to IP69K. Constructed with Sun's floating style design, this cartridge minimizes internal binding risks due to installation torque or machining variations in cavity/cartridge interfaces. It fits into cavity T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The valve has an impressive switching frequency of up to 15,000 cycles per hour and a typical response time of 50 milliseconds, making it suitable for rapid cycling applications. The model weighs approximately 0.60 lb (0.30 kg) and requires an installation torque between 30-35 lbf-ft (41-47 Nm).

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.
