The Sun Hydraulics DNCADBV712N (DNCADBV712N) 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, effectively minimizing oil loss during shifting\u2014a critical feature in pilot control circuits. Designed for robust and reliable operation, the DNCADBV712N has a flow capacity of 8 gpm/30 L/min with port 3 as the inlet and port 1 as the tank. It supports a maximum operating pressure of 5000 psi/350 bar and offers a rapid response time of approximately 50 ms. This valve is engineered for durability and performance under demanding conditions. The solenoid tube assembly is fatigue rated for high-pressure service, ensuring longevity even under rigorous use. Additionally, its wet armature design allows the working fluid to surround the armature which is crucial when the coil is energized for extended periods. Users should note that some fluids may degrade at higher temperatures, potentially affecting valve performance. The DNCADBV712N accommodates various coil termination and voltage options to suit different operational needs and environments. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to enhance flexibility in installation and use. The valve also features IP69K-rated coil connector options for superior environmental protection. Incorporating Sun\u2019s floating style construction minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. This design choice enhances reliability and extends the operational life of the valve by reducing mechanical stress. Overall, the Sun Hydraulics DNCADBV712N offers precise control, adaptable configurations, and robust construction making it an ideal choice for sophisticated hydraulic systems requiring efficient directional 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.
