The Sun Hydraulics DNCALJN924 (DNCALJN924) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precision hydraulic system applications. This direct-acting, balanced spool directional valve ensures a closed transition between positions, significantly minimizing oil loss during shifting which is crucial in maintaining the efficiency of pilot control circuits. The valve's design allows for port 3 to be used as the inlet and port 1 as the tank outlet; however, while reverse flow is possible through the valve, optimal performance in this configuration isn't guaranteed. Engineered for durability and reliability, the DNCALJN924 features a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it suitable for high-pressure applications. The valve does not require a minimum hydraulic pressure to operate due to its direct actuation mechanism. It incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. The DNCALJN924 benefits from a wet armature design where the working fluid surrounds the armature. This could be critical when considering coil energization duration as prolonged exposure can lead to fluid degradation at elevated temperatures. With its efficient magnetic design, the solenoid delivers high spool actuating force per watt expended which aids in reliable valve shifting. The unit also supports a variety of coil termination and voltage options including models with surge protection. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products and various connector options that offer up to IP69K ratings for enhanced environmental protection. The floating style construction of this model minimizes internal part binding risks caused by excessive installation torque or machining variations in cavity/cartridge setups. In summary, the Sun Hydraulics DNCALJN924 offers robust performance and versatility making it an excellent choice for sophisticated hydraulic systems requiring precise control and reliability under high-pressure 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.
