The Sun Hydraulics DNDAXHV71299 (DNDAXHV71299) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This valve operates efficiently with no minimum hydraulic pressure requirement, making it versatile for various applications. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring reliability under high-pressure conditions. It incorporates a wet armature design where the working fluid surrounds the armature, which can impact fluid stability if the coil is energized for extended periods. Notably, this cartridge offers multiple manual override options, although not all are compatible with weatherized coils; specific configurations allow temporary actuation via detent mechanisms with a mechanical life expectancy of around 7,000 cycles. The DNDAXHV71299 valve includes interchangeable coils with other Sun Series 1 solenoid products and supports installation in either direction. These coils offer various termination and voltage options, some with surge protection, and can achieve ratings up to IP69K for enhanced environmental resilience. The valve\u2019s unique magnetic design provides high efficiency by maximizing spool actuating force per watt expended. Additional features include Sun\u2019s floating style construction that minimizes internal binding due to excessive torque or machining variations. The valve fits into a T-31A cavity and supports flow capacities up to 10 gpm (40 L/min) with typical response times of 50 ms. It handles maximum operating pressures of 5000 psi (350 bar) and exhibits minimal leakage at specified conditions. The DNDAXHV71299 is designed for high-frequency switching up to 15,000 cycles per hour and requires specific manual override force and stroke parameters. Seal kits are available in Viton material for both cartridge and coil components to ensure compatibility with different fluids.

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.
