The Sun Hydraulics DNDATZV628 (DNDATZV628) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is fatigue-rated for service up to 5000 psi (350 bar) and does not require minimum hydraulic pressure for operation. It features a wet armature design, enhancing reliability by allowing the working fluid to cool the coil, although caution should be taken with fluids prone to thermal breakdown. The DNDATZV628 offers multiple manual override options, including models with temporary actuation detents and a mechanical life expectancy of around 7,000 cycles. This valve is compatible with EPDM seals specifically for phosphate ester fluid systems. The cartridge's design includes interchangeable coils with Sun Series 1 products and supports various voltage options with or without surge protection. Coil connector options can achieve ratings up to IP69K for superior environmental protection. The high-efficiency solenoid delivers robust spool actuating force per watt, ensuring dependable valve switching performance. The Sun floating style construction minimizes internal binding risks due to installation torque or machining variations. This model fits in cavity T-31A and belongs to Series 1, offering a capacity of up to 10 gpm (40 L/min). It exhibits typical response times of approximately 50 ms and handles maximum leakage rates at specified conditions. The valve supports a switching frequency of up to 15,000 cycles per hour and requires specific manual override forces and strokes for operation. Its compact build features a solenoid tube diameter of .75 inches (19 mm) and weighs .60 lb (.30 kg), making it suitable for various hydraulic system applications requiring efficient directional control.

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.
