The Sun Hydraulics DNDATTV928 (DNDATTV928) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. It features a fatigue-rated solenoid tube assembly capable of withstanding 5000 psi (350 bar) service pressure. This valve operates without needing minimum hydraulic pressure and offers several manual override options, although these are not compatible with weatherized coils. The manual override mechanisms have a life expectancy of around 7,000 cycles and require specific force requirements for operation. The valve is suitable for use in systems with phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids will damage the seals. The wet armature design allows the working fluid to surround the armature, which can be affected by the heat generated during prolonged coil energization. The solenoid's unique magnetic design ensures high efficiency and reliable valve shifting by providing significant spool actuating force per watt expended. This model also incorporates Sun's floating style construction to reduce internal part binding risks due to installation torque or machining variations. The DNDATTV928 has a capacity of 10 gpm (40 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). It has a typical response time of 50 ms and maximum valve leakage at specified conditions is limited to 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. Various coil termination and voltage options are available, including those with surge protection, and coils are interchangeable with other Sun Series 1 solenoid products.

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.
