The Sun Hydraulics DNCADSN72419 (DNCADSN72419) is a high-performance, solenoid-operated directional valve that offers precise control in hydraulic systems. This 4-way, 2-position cartridge valve features a direct-acting, balanced spool with a closed transition between positions, minimizing oil loss during shifting. This characteristic is particularly beneficial for pilot control circuits where maintaining hydraulic integrity is crucial. Engineered for robust performance, the DNCADSN72419 operates without requiring a minimum hydraulic pressure and has a valve capacity rated at 8 gpm (30 L/min), with port 3 as the inlet and port 1 as the tank. Although it allows reverse flow, optimal performance in this configuration is not assured. The solenoid tube assembly of this model is fatigue rated for service up to 5000 psi (350 bar), ensuring reliable operation under high-pressure conditions. The DNCADSN72419 uses EPDM seals when configured for systems with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Its wet armature design means that the working fluid surrounds the armature, potentially affecting fluid integrity if exposed to heat over extended periods. This model boasts a variety of coil voltage and termination options, including designs with surge protection and environmental shielding options like IP69K-rated connectors for enhanced durability against harsh conditions. The solenoid's innovative magnetic design enhances efficiency, providing high spool actuating force per watt expended which ensures reliable valve actuation. Additionally, its construction incorporates Sun's floating style design which helps prevent internal parts binding due to installation torque or variations in cavity/cartridge machining. With interchangeable coils compatible with other Sun Series 1 solenoid products and a manual override feature, this valve offers flexibility and ease of maintenance in various industrial applications.

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.
