The Sun Hydraulics DNDATHV548 (DNDATHV548) is a solenoid-operated 4-way, 2-position cartridge valve designed for high-efficiency directional control in hydraulic systems. This direct-acting, balanced spool valve does not require a minimum hydraulic pressure for operation, making it versatile and adaptable to various applications. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring durability under demanding conditions. The valve's wet armature design allows the working fluid to surround the armature, aiding in heat dissipation generated by the coil during long periods of energization. This model offers several manual override options, including configurations without manual override capability. For models with D or L control options, the detent mechanism in the manual override is intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The cartridge can be equipped with EPDM seals suitable for phosphate ester fluids but should avoid petroleum-based substances to prevent seal damage. The DNDATHV548 incorporates Sun's unique floating style construction to reduce potential internal binding from excessive installation torque or machining variations within the cavity/cartridge interface. It supports a wide variety of coil termination and voltage options, some with surge protection features, and allows coil interchangeability with other Sun Series 1 solenoid products. Coil connectors are rated up to IP69K for enhanced environmental protection. Capable of handling flow rates up to 10 gpm (40 L/min) and featuring a typical response time of 50 ms, this valve is designed for reliable performance across numerous applications requiring efficient fluid control. Its high switching frequency capability of up to 15,000 cycles per hour further underscores its suitability for dynamic operational environments where consistent performance is critical.

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.
