The Sun Hydraulics DNCADLV (DNCADLV) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for precise control in hydraulic systems. It features a closed transition between positions, minimizing oil loss during shifting which is crucial for maintaining efficiency in pilot control circuits. The valve's unique construction allows port 3 to serve as the inlet and port 1 as the tank outlet; however, it is capable of reverse flow under certain conditions. Engineered for durability and performance, the DNCADLV can handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 8 gpm (30 L/min). The solenoid tube assembly of this model is fatigue rated for high-pressure service, ensuring reliability under demanding conditions. It requires no minimum hydraulic pressure to operate, making it versatile across various applications. The DNCADLV utilizes EPDM seals specifically for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Its wet armature design means the working fluid surrounds the armature which could be subject to heat during prolonged coil energization. This factor should be considered when using certain fluid types that may degrade under heat. Additionally, this model offers a variety of coil termination and voltage options including configurations with surge protection. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Connector options provide environmental protection ratings up to IP69K. Incorporating Sun's floating style construction minimizes internal parts binding due to installation torque or machining variations in the cavity/cartridge setup. With its robust design and flexible configuration options, the DNCADLV provides reliable performance and adaptability suitable for complex hydraulic systems.

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.
