The Sun Hydraulics DNCADLV814 (DNCADLV814) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, significantly minimizing oil loss during shifting\u2014a critical feature for maintaining efficiency in pilot control circuits. With a capacity of 8 gallons per minute (30 liters per minute), the DNCADLV814 operates efficiently with port 3 as the inlet and port 1 as the tank. It is engineered to handle a maximum operating pressure of 5000 psi (350 bar), and its solenoid tube assembly is fatigue rated for the same, ensuring durability and long-term performance under demanding conditions. The valve's response time is notably quick at approximately 50 milliseconds, and it can handle up to 15,000 switching cycles per hour. This model incorporates Sun Hydraulics' floating style construction which reduces risks of internal parts binding due to installation torque or variations in cavity/cartridge machining. Additionally, the wet armature design means that the working fluid surrounds the armature; while this helps in certain applications, it requires consideration regarding fluid type as some may degrade at higher temperatures. The DNCADLV814 supports various coil termination and voltage options including designs with surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For environmental resilience, additional weatherized coils and kits are available to provide enhanced protection against harsh conditions. Designed for versatility and robust operation across various hydraulic applications, this valve ensures reliable performance with minimal maintenance requirements. Its manual override features are user-friendly with only a modest force requirement for operation, making it an efficient choice for system designers seeking reliable hydraulic control solutions.

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.
