The Sun Hydraulics DNDATHN928 (DNDATHN928) 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 features a direct-actuated mechanism that requires no minimum hydraulic pressure for operation. It offers several manual override options, although the functionality is not compatible with weatherized coils. For models with D or L control, the manual override's detent mechanism is intended for temporary actuation with an approximate mechanical life of 7,000 cycles. The cartridge's EPDM seals are suitable for systems using phosphate ester fluids but are susceptible to damage from petroleum-based fluids. Utilizing a wet armature design, the valve surrounds the armature with working fluid, which can be exposed to coil-generated heat over extended energization periods\u2014potentially affecting certain fluids like water-glycol mixtures. The solenoid's unique magnetic design provides high efficiency by maximizing spool actuating force per watt expended, ensuring reliable valve shifting. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted in either direction on the tube. Coil connector options offer protection ratings up to IP69K, and additional weatherized coils and kits are available for enhanced environmental protection. The valve incorporates Sun's floating style construction to minimize internal part binding due to installation torque or machining variations. The DNDATHN928 has a cavity size of T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). It supports a maximum operating pressure of 5000 psi (350 bar) and has a typical response time of 50 ms. The maximum valve leakage at 110 SUS (24 cSt) is rated at 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), while its switching frequency reaches up to 15,000 cycles per hour.

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.
