The Sun Hydraulics DNCADSN298 (DNCADSN298) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed for robust and efficient operation in demanding hydraulic systems. It features a closed transition between positions to minimize oil loss during shifting, which is critical in maintaining the efficiency and performance of pilot control circuits. The DNCADSN298 valve offers a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 8 gpm (30 L/min), making it suitable for a wide range of hydraulic applications. The valve's solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and long life under rigorous conditions. Furthermore, it operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. This model incorporates EPDM seals when configured for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Additionally, the DNCADSN298 utilizes a wet armature design where the working fluid surrounds the armature. This design consideration is vital as prolonged energization of the coil may lead to fluid breakdown, particularly with water-glycol mixtures, potentially affecting cartridge functionality due to varnish formation. The valve also boasts a variety of coil termination and voltage options, including models with surge protection and IP69K-rated connectors for enhanced environmental resistance. Its magnetic design delivers high efficiency with greater spool actuating force per watt expended. The interchangeable coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. In summary, the Sun Hydraulics DNCADSN298 offers exceptional performance and flexibility for advanced hydraulic systems requiring reliable directional control and minimal operational losses under various environmental 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.
