The Sun Hydraulics DNCADWV848 (DNCADWV848) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool directional valve ensures smooth transitions with a closed transition between positions, which minimizes oil loss during shifting\u2014a critical feature in pilot control circuits. With a valve capacity based on port 3 as the inlet and port 1 as the tank, this model offers reverse flow capabilities, though performance consistency in reverse flow is not guaranteed. The DNCADWV848 operates without requiring a minimum hydraulic pressure and features a fatigue-rated solenoid tube assembly for pressures up to 5000 psi (350 bar). It incorporates EPDM seals specifically for use with phosphate ester fluids; however, exposure to petroleum-based fluids will damage these seals. The wet armature design of the valve means that the working fluid surrounds the armature, potentially affecting fluid integrity under prolonged energization due to heat exposure. This model boasts various coil termination and voltage options and can accommodate environmental protection needs with additional weatherized coils and kits. Its unique magnetic design enhances solenoid efficiency, providing reliable valve shifting by maximizing spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoid products and can be oriented in either direction during mounting. Key specifications include an operating capacity of 8 gpm (30 L/min), maximum operating pressure of 5000 psi (350 bar), and typical response time of 50 ms. The DNCADWV848 also features Sun's floating style construction which reduces risks of internal parts binding due to installation torque or cavity/cartridge machining variations. This model is an essential component for systems requiring robust performance with high reliability in directional control applications.

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.
