The Sun Hydraulics DNCADCV748 (DNCADCV748) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in diverse applications. Featuring a direct-acting, balanced spool with closed transition between positions, this valve minimizes oil loss during shifting which is crucial in maintaining efficiency particularly in pilot control circuits. It offers a robust configuration with port 3 as the inlet and port 1 as the tank, though reverse flow is feasible but not recommended for optimal performance. The DNCADCV748 is engineered to operate without minimum hydraulic pressure and incorporates EPDM seals specifically for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. The valve's wet armature design allows the working fluid to surround the armature, potentially affecting fluid integrity under prolonged coil energization. It supports a variety of coil termination and voltage options, enhancing adaptability across different systems. Additionally, this model boasts an efficient magnetic design that enhances solenoid performance by maximizing spool actuating force per watt expended. This feature ensures reliable valve shifting even under demanding conditions. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Options for coil connectors are extensive with ratings up to IP69K for higher environmental resilience. Sun Hydraulics has also integrated their floating style construction into the DNCADCV748 to reduce internal part binding risks caused by installation torque or cavity/cartridge machining variations. This model\u2019s specifications include an 8 gpm (30 L/min) capacity, maximum operating pressure of 5000 psi (350 bar), and quick response times typical at 50 ms. With its comprehensive features tailored for high-stress environments, the DNCADCV748 stands out as a reliable component in advanced hydraulic systems.

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.
