The Sun Hydraulics DNCADTV828 (DNCADTV828) 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 features a closed transition between positions, which significantly minimizes the loss of oil during shifting. This characteristic is especially beneficial in pilot control circuits where maintaining fluid integrity is critical. With a capacity of 8 gpm/30 L/min and a maximum operating pressure of 5000 psi/350 bar, the DNCADTV828 is engineered to handle demanding applications efficiently. The valve offers flexibility with reverse flow capabilities, although it is optimized for standard flow directions for peak performance. The solenoid tube assembly of this model is fatigue rated for high-pressure service, ensuring durability and long-term reliability. This model requires no minimum hydraulic pressure for operation due to its direct actuation design. It features EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Additionally, the DNCADTV828 utilizes a wet armature design where the working fluid surrounds the armature\u2014this needs consideration regarding fluid type and operational duration as heat build-up can affect certain fluid properties. For customization and adaptability in various system configurations, Sun Hydraulics offers a range of coil termination and voltage options for this model, including versions with surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The robust construction includes Sun\u2019s floating style design which minimizes internal part binding due to installation or machining variances. Overall, the DNCADTV828 provides robust performance and reliable operation for hydraulic applications requiring precise directional control and efficient fluid handling.

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.
