The Sun Hydraulics DNDAMYN71299 (DNDAMYN71299) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This valve is engineered for robust performance with a solenoid tube assembly fatigue rated for 5000 psi (350 bar) service, ensuring durability in demanding hydraulic applications. It operates without requiring any minimum hydraulic pressure, making it versatile for various system configurations. The cartridge offers multiple manual override options, although note that manual override functionality is not compatible with weatherized coils. The manual control assembly on models with D or L control features a detent mechanism designed for temporary actuation and has an estimated mechanical life of approximately 7,000 cycles. The valve incorporates EPDM seals suitable for systems using phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Utilizing a wet armature design, the working fluid surrounds the armature and may be affected by coil-generated heat during prolonged energization. This characteristic requires consideration when using certain fluids like water-glycol mixtures that degrade under such conditions. This high-efficiency solenoid generates significant spool actuating force per watt expended, ensuring reliable valve shifting. It supports interchangeable coils compatible with other Sun Series 1 products and can be mounted in either direction. Coil connector options provide ratings up to IP69K, offering enhanced environmental protection when needed. The valve is designed with Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. It features a T31A cavity and offers a capacity of 10 gpm (40 L/min). With a typical response time of 50 ms and maximum operating pressure of 5000 psi (350 bar), this valve is well-suited for high-frequency switching applications up to 15,000 cycles/hour. Its compact dimensions include a solenoid tube diameter of .75 inches (19 mm) and an installation torque requirement of 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.
