The Sun Hydraulics DNCALXN224 (DNCALXN224) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct acting, balanced spool directional control. This valve features a closed transition between positions, significantly reducing oil loss during shifting\u2014a critical aspect in pilot control circuits. The valve's capacity is optimized with port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended due to performance limitations. The solenoid tube assembly can withstand pressures up to 5000 psi (350 bar), making it suitable for high-pressure applications without requiring minimum hydraulic pressure for operation. This valve employs EPDM seals compatible with systems using phosphate ester fluids; however, they are vulnerable to damage from petroleum-based fluids. With a wet armature design, the working fluid surrounds and cools the armature, though prolonged coil energization can lead to fluid breakdown in certain mixtures like water-glycol. A variety of coil termination and voltage options are available, offering flexibility in application along with surge protection features. The high-efficiency magnetic design of the solenoid ensures reliable valve shifting by maximizing spool actuating force per watt. The DNCALXN224 incorporates Sun's floating style construction to minimize internal binding risks due to installation torque or machining variations. It supports a maximum flow capacity of 8 gpm (30 L/min) and a maximum operating pressure of 5000 psi (350 bar). The response time averages around 50 ms with a switching frequency capability of up to 15,000 cycles per hour. Manual override requires minimal force and stroke distance for user convenience. This model is compatible with interchangeable coils from Sun Series 1 products and offers robust environmental protection through IP69K-rated coil connectors and additional weatherized options.

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.
