The Sun Hydraulics DNCALJN72419 (DNCALJN72419) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool valve ensures a closed transition between positions, minimizing oil loss during shifting, which is especially beneficial in pilot control circuits. The valve's operation does not require a minimum hydraulic pressure, making it versatile for various applications. With a capacity of 8 gpm/30 L/min and maximum operating pressure of 5000 psi/350 bar, the DNCALJN72419 is built to handle demanding tasks. Its robust solenoid tube assembly is fatigue rated for high-pressure service up to 5000 psi. The valve features a wet armature design where the working fluid surrounds the armature; this is crucial in scenarios where the coil may be energized for extended periods as it can affect fluid integrity over time. This model incorporates Sun's floating style construction which reduces risks of internal parts binding due to installation torque or cavity/cartridge machining variations. It offers rapid response times typically around 50 ms and maintains operational reliability with a switching frequency of up to 15000 cycles per hour. Additionally, the manual override features require minimal force, enhancing ease of use under various conditions. For environmental adaptability, it supports multiple coil termination and voltage configurations with options for surge protection and weatherized coils for enhanced protection against harsh conditions. Seal options include EPDM for phosphate ester fluids compatibility while avoiding exposure to petroleum-based substances which could damage the seals. Overall, the DNCALJN72419 provides reliable performance and flexibility suited for advanced hydraulic systems requiring precise directional control and enduring operation under high pressures and variable 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.
