The Sun Hydraulics DNCADCN72419 (DNCADCN72419) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve features a closed transition between positions, which significantly minimizes oil loss during shifting\u2014a crucial aspect in pilot control circuits. With an inlet at port 3 and the tank at port 1, the valve facilitates a capacity of 8 gpm/30 L/min and supports a maximum operating pressure of 5000 psi/350 bar. Although reverse flow is possible through this configuration, optimal performance under such conditions is not assured. The DNCADCN72419 is engineered with durability in mind; its solenoid tube assembly is fatigue rated for demanding 5000 psi/350 bar applications. Designed to operate without minimum hydraulic pressure, the valve offers flexibility in various hydraulic setups. It incorporates EPDM seals suitable for systems using phosphate ester fluids but cautions against exposure to petroleum-based substances which could damage the seals. This model employs a wet armature design where the working fluid surrounds the armature. Extended energization of the coil can lead to heat generation affecting fluid integrity over time. The valve\u2019s magnetic design enhances solenoid efficiency, ensuring high spool actuating force per watt expended for reliable shifting. It also features interchangeable coils with other Sun Series 1 solenoid products and offers multiple coil connector options rated up to IP69K for environmental resilience. Additional attributes include a switching frequency of up to 15000 cycles/hr and a rapid typical response time of approximately 50 ms. The manual override requires minimal force and has a short stroke distance for operational convenience. Its robust construction using Sun\u2019s floating style minimizes internal part binding due to installation or machining variations, ensuring consistent performance and longevity.

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.
