The Sun Hydraulics DNCADXN248 (DNCADXN248) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve that offers precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly reduces oil loss during shifting. This characteristic is particularly beneficial in pilot control circuits where maintaining hydraulic integrity is crucial. Designed for robust performance, the DNCADXN248 valve has a capacity of 8 gpm/30 L/min and can handle maximum operating pressures up to 5000 psi/350 bar. It is engineered with a fatigue-rated solenoid tube assembly for long-term durability under demanding conditions. The valve's quick response time of approximately 50 ms and its ability to handle up to 15,000 switching cycles per hour make it suitable for high-frequency applications. The DNCADXN248 employs EPDM seals configured specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Its wet armature design means that the working fluid surrounds the armature which could be a factor when the coil is energized for extended periods as it leads to heat buildup that can degrade certain types of hydraulic fluids. This model also features interchangeable coils with other Sun Series 1 solenoid products and offers various coil termination and voltage options, including models with surge protection. Coils can be mounted on the tube in either direction and connector options are available up to IP69K for enhanced environmental protection. Sun Hydraulics' innovative floating style construction minimizes potential internal binding due to installation torque or machining variations in the cavity/cartridge setup. This ensures reliable operation and longevity of the valve even under variable installation conditions.

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.
