The Sun Hydraulics DNCADXV72419 (DNCADXV72419) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve engineered for precise hydraulic fluid control with a balanced spool directional mechanism. This direct-acting valve features a closed transition between positions, significantly reducing oil loss during shifts which is crucial in maintaining efficiency in pilot control circuits. The valve\u2019s design allows for port 3 to be used as the inlet and port 1 as the tank outlet, although it does support reverse flow under certain conditions. With a robust solenoid tube assembly rated for fatigue at up to 5000 psi (350 bar), the DNCADXV72419 ensures reliable operation under high-pressure conditions without requiring minimum hydraulic pressure. The wet armature design of the valve means that the working fluid surrounds the armature, which could affect fluid integrity if exposed to heat for extended periods. It is particularly noted that this model should not be used with petroleum-based fluids due to its EPDM seal configuration but is suitable for systems using phosphate ester fluids. The DNCADXV72419 offers versatile coil termination and voltage options, including models with surge protection. Its magnetic design enhances solenoid efficiency by providing high spool actuating force per watt expended. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Connector options are available up to IP69K standards for environmental protection. This model incorporates Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 8 gpm (30 L/min), it delivers rapid response times typical at 50 ms and maintains low leakage rates even under high pressure. The DNCADXV72419 is designed for durability and reliability in demanding hydraulic 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.
