The Sun Hydraulics DNCADSN548 (DNCADSN548) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve ensures efficient operation with its closed transition between positions, significantly minimizing oil loss during shifting\u2014ideal for pilot control circuits where maintaining hydraulic integrity is critical. The valve offers a robust design with a capacity based on port 3 as the inlet and port 1 as the tank, though it allows for reverse flow under certain conditions. Engineered to operate without minimum hydraulic pressure, the DNCADSN548 features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for demanding applications. Its wet armature design allows the working fluid to surround the armature, which could be crucial when considering the thermal effects during prolonged energization periods. This model comes equipped with EPDM seals specifically for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage these seals. The DNCADSN548 valve is known for its fast response time of approximately 50 ms and supports a high switching frequency of up to 15,000 cycles per hour. It also incorporates Sun Hydraulics' unique floating style construction that prevents internal parts from binding due to installation torque or cavity/cartridge machining variations. The range of coil termination and voltage options available enhances its versatility while maintaining environmental protection standards up to IP69K. With an installation torque requirement between 30 \u2013 35 lbf ft (41 \u2013 47 Nm) and weighing just 0.60 lb (0.30 kg), this compact yet powerful valve is easy to handle and install in various hydraulic setups. Its manual override features are straightforward, requiring minimal force and providing quick intervention capabilities in system adjustments or emergencies.

This solenoid-operated, 4-way, 2-position cartridge is a direct-acting, balanced spool directional valve. The transition between positions is closed. The closed transition greatly reduces the loss of oil when shifting which can be of particular importance in pilot control circuits.
- Valve capacity is based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible, the same performance cannot be guaranteed and is not recommended.
- 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.
- Cartridges configured 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.
