The Sun Hydraulics DNCADBV812 (DNCADBV812) is a high-performance solenoid-operated, 4-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, significantly minimizing oil loss during shifting, which is especially beneficial in pilot control circuits. The valve\u2019s configuration enables port 3 to serve as the inlet and port 1 as the tank outlet, though it supports reverse flow with noted limitations on performance. Constructed to handle a maximum operating pressure of 5000 psi (350 bar) and a flow capacity up to 8 gpm (30 L/min), the DNCADBV812 is versatile for various hydraulic applications. Its solenoid tube assembly is fatigue rated for demanding conditions, ensuring reliability even under continuous high-pressure operation. The valve operates without requiring a minimum hydraulic pressure and incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based substances. The wet armature design of the DNCADBV812 means that the working fluid surrounds the armature, which can affect fluid properties if the coil remains energized over extended periods. This model also boasts rapid response times typically around 50 ms and maintains operational integrity up to a switching frequency of 15,000 cycles per hour. For enhanced adaptability in various systems, Sun Hydraulics offers an array of coil termination and voltage options for this model, including designs with surge protection. These coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, the valve features Sun\u2019s floating style construction which minimizes internal parts binding caused by installation variations or excessive torque. Overall, the DNCADBV812 provides precise control and reliable operation in hydraulic systems requiring efficient directional control of fluid flow under high pressure conditions.

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.
