The Sun Hydraulics DNDATRN628 (DNDATRN628) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This model is fatigue-rated for service pressures up to 5000 psi (350 bar) and operates without the need for a minimum hydraulic pressure. It features multiple manual override options, though these are not compatible with weatherized coils. The manual control assembly has a mechanical life expectancy of approximately 7,000 cycles. This valve is equipped with EPDM seals suitable for systems using phosphate ester fluids; however, these seals are not compatible with petroleum-based fluids. The wet armature design allows the working fluid to cool the coil but may lead to varnish formation in certain fluids like water-glycol mixtures over time. The solenoid's magnetic design enhances efficiency by providing high spool actuating force per watt, ensuring reliable valve operation. The DNDATRN628 offers various coil termination and voltage options, some with surge protection, and interchangeable coils compatible with other Sun Series 1 solenoid products. Coil connector options can achieve ratings up to IP69K for enhanced environmental protection. The valve incorporates Sun's floating style construction to reduce binding risks from excessive installation torque or machining variations. It fits into a T-31A cavity and supports a flow capacity of 10 gpm (40 L/min). Typical response time is 50 ms, with maximum leakage at 10 in\u00b3/min (160 cc/min) at 3000 psi (210 bar). The valve can handle switching frequencies up to 15,000 cycles per hour and requires manual override force of approximately 5 lbs/1000 psi at Port 1. Installation torque ranges from 30-35 lbf ft (41-47 Nm), and the model weighs around .60 lb (.30 kg). Seal kits are available in Viton material for both cartridge and coil applications.

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.
