The Sun Hydraulics DNCALBV624N (DNCALBV624N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool with closed transition between positions. This design minimizes the loss of oil during shifting, which is critical in maintaining efficiency in pilot control circuits. The valve is engineered for robust performance with a capacity of 8 gpm/30 L/min and can handle a maximum operating pressure of 5000 psi/350 bar. Notably versatile, the DNCALBV624N valve allows for reverse flow but does so with a caveat regarding optimal performance. Its solenoid tube assembly is fatigue rated for high-pressure service up to 5000 psi/350 bar, ensuring long-term durability and reliability even under demanding conditions. The valve operates without requiring a minimum hydraulic pressure, facilitating its use in various applications. This model incorporates EPDM seals specifically designed for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. The wet armature design of the valve means that the working fluid surrounds the armature which could be susceptible to heat during prolonged energization \u2014 an important consideration depending on the fluid used. For customization and adaptability to different systems, Sun Hydraulics offers a variety of coil termination and voltage options including models with surge protection. The coils are interchangeable with other Sun Series 1 solenoid products and can be configured in either direction on the tube. Additional features like IP69K-rated connector options and weatherized coils enhance the DNCALBV624N\u2019s environmental resilience. Overall, the DNCALBV624N is built to offer reliable and efficient performance with flexible installation options suited for various hydraulic applications requiring precise control and minimal fluid loss during operation transitions.

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.
