The Sun Hydraulics DNCADWN724 (DNCADWN724) 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 to minimize oil loss during shifting, which is crucial for maintaining efficiency in pilot control circuits. The valve is capable of operating with no minimum hydraulic pressure required, making it versatile for various applications. With a robust design that includes a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, the DNCADWN724 ensures reliable performance even under demanding conditions. It supports a flow capacity of 8 gpm (30 L/min) based on port 3 as the inlet and port 1 as the tank. Although reverse flow is possible through the valve, optimal performance in this mode is not guaranteed. The valve's wet armature design allows the working fluid to surround the armature, which can be significant when considering fluid compatibility and coil energization duration. Special attention should be given to fluid selection as certain fluids like water-glycol mixtures may degrade at high temperatures generated by prolonged coil energization. For customization and integration ease, Sun Hydraulics offers a variety of coil termination and voltage options for the DNCADWN724, including configurations with surge protection. The coils are interchangeable with other Sun Series 1 solenoid products and feature IP69K rated connector options for enhanced environmental protection. This model also incorporates Sun's floating style construction to prevent internal part binding due to installation torque or machining variations of cavity/cartridge. With its quick response time of approximately 50 ms and maximum operating pressure of 5000 psi (350 bar), the DNCADWN724 provides efficient and reliable operation suitable for advanced hydraulic system 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.
