The Sun Hydraulics DNDATTV712N (DNDATTV712N) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool directional design. It is engineered for high-pressure applications with a fatigue rating of up to 5000 psi (350 bar), making it suitable for demanding hydraulic systems. The valve operates without the need for minimum hydraulic pressure, enhancing its versatility in various settings. It offers multiple manual override options, although manual override is not compatible with weatherized coils. For models with 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, exposing it to coil-generated heat. This can impact fluids like water-glycol mixtures over time due to potential breakdown at elevated temperatures. The solenoid's unique magnetic design enhances efficiency by providing high spool actuating force per watt expended, ensuring reliable valve operation. A variety of coil termination and voltage options are available, including those with surge protection. The DNDATTV712N incorporates Sun's floating style construction to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. It fits into cavity T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). The valve's typical response time is 50 ms and it supports a maximum switching frequency of 15,000 cycles per hour. Its maximum leakage at 110 SUS (24 cSt) is rated at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). With interchangeable coils compatible with other Sun Series 1 products and an IP69K rating for certain connector options, this valve offers robust environmental protection and flexibility in configuration.

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.
