The Sun Hydraulics DNCALAV223 (DNCALAV223) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. It features a closed transition between positions, significantly minimizing oil loss during shifting\u2014this is particularly advantageous in pilot control circuits where maintaining hydraulic integrity is crucial. The valve is designed with port 3 as the inlet and port 1 as the tank outlet, though it allows for reverse flow under certain conditions. This model operates without requiring a minimum hydraulic pressure and has been fatigue rated for up to 5000 psi (350 bar) service, making it robust for high-pressure applications. The DNCALAV223 incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage by petroleum-based fluids. Its wet armature design implies that the armature is immersed in the working fluid, potentially impacting fluid integrity if exposed to prolonged heat from an energized coil. This factor should be considered when using fluids like water-glycol mixtures that could degrade under such conditions. Sun Hydraulics has equipped this valve with various coil termination and voltage options\u2014including models with surge protection\u2014to cater to diverse operational needs. The solenoid of DNCALAV223 boasts a unique magnetic design that enhances efficiency and ensures reliable spool actuation. Additionally, its coils can be interchanged with other Sun Series 1 solenoid products and mounted in either direction on the tube. For environmental resilience, options are available for weatherized coils and kits. Furthermore, the construction of this model utilizes Sun's floating style which helps prevent internal parts from binding due to excessive installation torque or variations in cavity/cartridge machining.

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.
