The Sun Hydraulics DNDATJN812N (DNDATJN812N) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This versatile valve is fatigue-rated for service up to 5000 psi (350 bar) and does not require a minimum hydraulic pressure to operate. It offers several manual override options, although these are not compatible with weatherized coils. The manual override's detent mechanism is suitable for temporary actuation and has an approximate mechanical life expectancy of 7,000 cycles. The valve features a wet armature design that exposes the armature to the working fluid and heat generated by the coil, which can affect certain fluids like water-glycol mixtures over time. The DNDATJN812N provides high efficiency with its unique magnetic design that yields substantial spool actuating force per watt expended. This ensures reliable valve shifting even under demanding conditions. The cartridge supports interchangeable coils from Sun Series 1 solenoid products, allowing installation in either direction and offering coil connector options with ratings up to IP69K for enhanced environmental protection. The valve's construction incorporates Sun\u2019s floating style design to minimize internal part binding due to excessive installation torque or machining variations. It fits into cavity T-31A and has a capacity of 10 gpm (40 L/min). Typical response time is around 50 ms, with maximum leakage at 110 SUS being 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The switching frequency can reach up to 15,000 cycles per hour. Manual override requires a force of approximately 5 lbs/1000 psi at Port 1, with an override stroke of .10 inches (2.5 mm). The valve measures .75 inches in solenoid tube diameter and weighs approximately .60 lbs (.30 kg). Seal kits are available separately for maintenance needs.

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.
