While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Sun Hydraulics directly.***
The Sun Hydraulics DNDATTN712 (DNDATTN712) is a solenoid-operated 4-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This valve is fatigue-rated for service pressures up to 5000 psi (350 bar) and does not require minimum hydraulic pressure to operate. It features multiple manual override options, although these are not compatible with weatherized coils. The manual control assembly has a life expectancy of around 7,000 cycles. EPDM seal options are available for systems using phosphate ester fluids, though they are not suitable for petroleum-based fluids. The wet armature design exposes the armature to working fluid heat, which could affect function in continuous operation with certain fluids like water-glycol mixtures. The high-efficiency solenoid provides strong spool actuating force per Watt, ensuring reliable valve operation. Coils can be interchanged with other Sun Series 1 solenoid products and mounted in either direction, offering a range of termination and voltage options with surge protection up to IP69K ratings. Additional weatherized coils are available for enhanced environmental protection. The floating style construction reduces the risk of internal binding from installation torque or machining variations. This valve fits into a T-31A cavity and is part of Series 1, with a capacity of 10 gpm (40 L/min). It offers a typical response time of 50 ms and maximum leakage of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). Capable of switching frequencies up to 15,000 cycles per hour, the manual override requires a force of approximately 5 lbs/1000 psi and has a stroke length of .10 inches (2.5 mm). The solenoid tube diameter is .75 inches (19 mm), with a hex size of .78 inches (22.2 mm) and installation torque between 30-35 lbf ft (41-47 Nm).

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.
