The Sun Hydraulics DNCADAV512 (DNCADAV512) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. This direct-acting, balanced spool directional valve features a closed transition between positions, which minimizes the loss of oil during shifting\u2014a crucial feature for maintaining efficiency and performance in pilot control circuits. With a capacity based on port 3 as the inlet and port 1 as the tank, the DNCADAV512 allows for reverse flow, although optimal performance under this condition is not guaranteed. The valve's robust design includes a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). Additionally, it operates without requiring a minimum hydraulic pressure, enhancing its versatility across different hydraulic systems. The DNCADAV512 is equipped with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Its wet armature design implies that the working fluid surrounds the armature which can be exposed to heat generated by the coil if energized for extended periods. Such conditions may degrade certain types of fluids like water-glycol mixtures. This model offers various coil termination and voltage options, including configurations with surge protection. The coils are interchangeable with other Sun Series 1 solenoid products and can be installed in either direction on the tube. Connection options for these coils can achieve ratings up to IP69K for enhanced environmental protection. Finally, the DNCADAV512 incorporates Sun\u2019s floating style construction which helps prevent internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature ensures reliable operation and longevity of the valve even under demanding installation 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.
