The Sun Hydraulics DNDATCV71299 (DNDATCV71299) is a solenoid-operated 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. This valve is engineered with a fatigue-rated solenoid tube assembly for 5000 psi (350 bar) service, making it robust and reliable for demanding applications. It operates without requiring any minimum hydraulic pressure, offering flexibility in various systems. The cartridge includes several manual override options, though manual override functionality is not compatible with weatherized coils. For models with the D or L control, the detent mechanism in the manual override is designed for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. The valve employs a wet armature design where the working fluid surrounds the armature, which can be affected by prolonged coil energization due to heat exposure. Fluids like water-glycol mixtures may degrade over time under such conditions, potentially impacting performance. A wide range of coil termination and voltage options are available to suit different requirements, and coils are interchangeable with other Sun Series 1 solenoid products. The unique magnetic design of the solenoid ensures high efficiency and reliable valve shifting. This model incorporates Sun's floating style construction to minimize binding from installation torque or machining variations. It fits into cavity T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The maximum operating pressure is rated at 5000 psi (350 bar), with typical response times around 50 ms. The valve's design allows for up to IP69K connector ratings for enhanced environmental protection.

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.
