The Sun Hydraulics DNCADWN924 (DNCADWN924) is a high-performance, solenoid-operated directional valve engineered for precise hydraulic fluid control in various applications. This 4-way, 2-position cartridge valve features a direct-acting, balanced spool design that ensures reliable operation without the need for minimum hydraulic pressure. The valve's closed transition between positions minimizes oil loss during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. With a robust capacity rated at 8 gpm (30 L/min) and capable of handling a maximum operating pressure of 5000 psi (350 bar), the DNCADWN924 is designed to meet rigorous performance demands. It supports reverse flow but operates optimally with port 3 as the inlet and port 1 as the tank outlet, cautioning against reverse configurations to maintain performance integrity. The solenoid tube assembly is notably fatigue-rated for high-pressure service up to 5000 psi. This model incorporates EPDM seals specifically suited for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it could damage these seals. The wet armature design of the solenoid means that the working fluid surrounds the armature\u2014this should be considered in applications where the coil may be energized for extended periods due to potential fluid breakdown from heat exposure. Sun Hydraulics has equipped the DNCADWN924 with various coil termination and voltage options, enhancing its adaptability across different setups and environmental conditions. Additional features like interchangeable coils with other Sun Series 1 products, IP69K rated connector options, and weatherized coils further enhance its utility and durability in diverse operational contexts. The valve also benefits from Sun's floating style construction which minimizes internal part binding due to installation variances or machining discrepancies.

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.
