The Sun Hydraulics DNDATDV71219 (DNDATDV71219) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This robust valve features a solenoid tube assembly fatigue rated for service up to 5000 psi (350 bar), making it suitable for demanding hydraulic applications. It operates without requiring a minimum hydraulic pressure, enhancing its versatility in various systems. The valve offers multiple manual override options; however, these are not compatible with weatherized coils. Its detent mechanism is intended for temporary actuation with a life expectancy of approximately 7,000 cycles. The DNDATDV71219 uses EPDM seals for compatibility with phosphate ester fluids while avoiding petroleum-based fluids to prevent seal damage. Its wet armature design allows the working fluid to surround the armature, which can be affected by heat from the coil over extended periods. This requires consideration of fluid types that might degrade at high temperatures. With a capacity of 10 gpm (40 L/min) and a maximum operating pressure of 5000 psi (350 bar), this valve ensures efficient flow control. It features a rapid response time of approximately 50 ms and maintains low leakage rates under specified conditions. The valve's switching frequency capability reaches up to 15,000 cycles per hour. The solenoid's magnetic design enhances efficiency by providing high spool actuating force relative to power consumption, ensuring reliable operation. Coils are interchangeable within Sun Series 1 products and offer various termination and voltage options with optional surge protection. Additionally, coil connectors can achieve ratings up to IP69K for enhanced environmental protection. Installation is facilitated by Sun's floating style construction that minimizes internal binding risks due to excessive torque or machining variations. The cartridge fits into T31A cavities and requires specific installation torque settings for optimal performance.

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.
