The Sun Hydraulics DNDAXDV71219 (DNDAXDV71219) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is capable of handling a maximum operating pressure of 5000 psi (350 bar) and features a solenoid tube assembly fatigue-rated for such service. It operates without requiring minimum hydraulic pressure, making it versatile for various applications. The cartridge offers multiple manual override options, although these are incompatible with weatherized coils; models with D or L control include a detent mechanism suitable for temporary actuation with an estimated 7,000-cycle mechanical life expectancy. When equipped with EPDM seals, the valve is compatible with phosphate ester fluids but should avoid petroleum-based substances to prevent seal damage. The design incorporates a wet armature system where the working fluid surrounds the armature and absorbs heat from the coil. This is an important consideration for systems where the coil remains energized over long periods, as certain fluids like water-glycol mixtures may degrade at elevated temperatures. A variety of coil termination and voltage configurations are available, some offering surge protection for enhanced reliability. The high-efficiency solenoid design ensures robust performance by delivering substantial spool actuating force per watt expended. Coils can be interchanged with other Sun Series 1 products and installed in either direction. For environmental resilience, coil connector options are rated up to IP69K, and additional weatherized coils and kits are available. The valve's floating style construction minimizes internal part binding due to excessive installation torque or machining variations in cavity or cartridge designs. It has a capacity of 10 gpm (40 L/min), responds typically within 50 ms, and handles up to 15,000 cycles per hour switching frequency.

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.
