The Sun Hydraulics DNCALBV812N (DNCALBV812N) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting operation with a balanced spool directional control mechanism. This model is distinguished by its closed transition between positions, which minimizes oil loss during shifting\u2014a crucial feature for maintaining efficiency in pilot control circuits. With a valve capacity determined by Port 3 as the inlet and Port 1 as the tank, the DNCALBV812N supports a maximum flow of 8 gpm (30 L/min) and can handle pressures up to 5000 psi (350 bar). The valve's solenoid tube assembly is fatigue rated for high-pressure service, enhancing its reliability and lifespan even under rigorous conditions. It also features a wet armature design where the working fluid surrounds the armature, potentially affecting fluid characteristics if exposed to prolonged heat from coil energization. Special attention is needed when using water-glycol mixtures as they may degrade under such conditions. Notably versatile in configuration, the DNCALBV812N offers various coil termination and voltage options, including models with surge protection. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For environments demanding higher durability, additional weatherized coils and kits are available to ensure comprehensive environmental protection. Furthermore, this model incorporates Sun\u2019s floating style construction which reduces risks associated with internal parts binding due to installation torque or cavity/cartridge machining variations. The rapid response time of typically 50 ms and switching frequency of up to 15,000 cycles per hour make this valve highly responsive and suitable for applications requiring frequent actuations. The DNCALBV812N also features manual override capabilities that require minimal force, ensuring easy operation even during manual adjustments.

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.
