The Sun Hydraulics DNCADCV72419 (DNCADCV72419) is a solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control. This direct-acting, balanced spool valve ensures a closed transition between positions, minimizing oil loss during shifting\u2014a critical feature in pilot control circuits. The valve is notably robust, with a fatigue rating for 5000 psi (350 bar) service, making it suitable for high-pressure applications. This model operates without requiring a minimum hydraulic pressure and incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage from exposure to petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature which may be relevant when considering the type of fluid used due to potential breakdown and varnish formation at high temperatures. The DNCADCV72419 offers flexibility in configuration with various coil termination and voltage options available, including models with surge protection. These coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Environmental durability is enhanced through optional weatherized coils and kits. Engineered for reliability and efficiency, the valve features a unique magnetic design that maximizes spool actuating force per watt expended. It also incorporates Sun\u2019s floating style construction which helps prevent internal parts binding due to installation torque or machining variations of cavity/cartridge. With specifications like an 8 gpm (30 L/min) capacity, rapid response time of approximately 50 ms, and manual override capabilities, this model is engineered for both effectiveness and ease of use in diverse hydraulic systems configurations.

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.
