The Sun Hydraulics DNCADSV848 (DNCADSV848) is a high-efficiency, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly minimizes oil loss during shifts\u2014an essential feature for maintaining efficiency in pilot control circuits. The valve is engineered to handle a flow capacity of 8 gpm (30 L/min) with port 3 as the inlet and port 1 as the tank, although it allows for reverse flow under certain conditions. Constructed to operate without a minimum hydraulic pressure requirement, the DNCADSV848 ensures reliable performance across various applications. Its solenoid tube assembly is fatigue rated for up to 5000 psi (350 bar), suitable for demanding operational environments. The valve incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. The unique magnetic design of the solenoid in the DNCADSV848 maximizes spool actuating force per watt expended, ensuring efficient and reliable valve shifting. This model also features interchangeable coils with other Sun Series 1 solenoid products and offers multiple coil termination and voltage options\u2014including models with surge protection. Weather-resistant coils and additional environmental protection kits further enhance its robustness. For installation flexibility and durability, this valve utilizes Sun\u2019s floating style construction which helps prevent internal parts from binding due to excessive installation torque or cavity/cartridge machining variations. With specifications like a maximum operating pressure of 5000 psi (350 bar), a rapid response time typical of 50 ms, and manual override capabilities, the DNCADSV848 stands out as an adaptable solution for various hydraulic systems requiring precise fluid control.

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.
