The Sun Hydraulics DNDATTV628 (DNDATTV628) is a solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. Engineered for reliability, the solenoid tube assembly is fatigue-rated for up to 5000 psi (350 bar), allowing it to function effectively without requiring a minimum hydraulic pressure. This cartridge valve offers various manual override options, although manual overrides are incompatible with weatherized coils. Models equipped with D or L control have a detent mechanism for temporary actuation with an approximate mechanical life expectancy of 7,000 cycles. For systems using phosphate ester fluids, EPDM seals are recommended; however, exposure to petroleum-based substances can damage these seals. The valve incorporates a wet armature design, allowing the working fluid to surround the armature and helping dissipate heat generated by the coil. Users should be cautious when using water-glycol mixtures as they may degrade over time due to heat exposure. The solenoid\u2019s magnetic design enhances efficiency by providing high spool actuating force per watt expended. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted in either direction on the tube. With coil connector options rated up to IP69K and additional weatherized coils available, users can achieve comprehensive environmental protection. This valve supports a flow capacity of up to 10 gpm (40 L/min) and has a response time of approximately 50 ms. It exhibits minimal leakage at maximum operating pressure conditions and allows for a switching frequency of up to 15,000 cycles per hour. The DNDATTV628 utilizes Sun's floating style construction to reduce internal part binding risks during installation or due to machining variations in cavity or cartridge components.

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.
