The Sun Hydraulics DNCALJN212N (DNCALJN212N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve featuring a direct-acting, balanced spool with closed transition between positions. This design substantially minimizes oil loss during shifting, which is crucial in pilot control circuits. The valve is engineered to function efficiently with port 3 as the inlet and port 1 as the tank outlet; however, it also supports reverse flow, albeit with potentially varied performance that is not recommended for optimal operation. This model boasts a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring durability and reliability in demanding service conditions. It operates without the need for minimum hydraulic pressure, enhancing its versatility across applications. The DNCALJN212N utilizes EPDM seals specifically designed for compatibility with phosphate ester fluids; these seals must avoid exposure to petroleum-based substances to prevent damage. A key feature of this valve is its wet armature design where the working fluid surrounds the armature. This can be a consideration when the coil is energized for extended periods as some fluids may degrade under prolonged heat exposure. Additionally, the valve offers a variety of coil termination and voltage options, including configurations with surge protection. These coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For further customization and environmental resilience, various weatherized coils and kits are available. The construction incorporates Sun's floating style to minimize internal parts binding due to installation torque or machining variations of cavity/cartridge. With its compact design offering an 8 gpm (30 L/min) capacity and quick response time of approximately 50 ms, along with manual override capabilities and multiple sealing options including Viton seals, the DNCALJN212N provides a reliable solution for efficient directional control in hydraulic systems.

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.
