The Sun Hydraulics DNCADWN212 (DNCADWN212) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for precise control in hydraulic systems. It features a closed transition between positions, which minimizes oil loss during shifting\u2014a critical factor in maintaining efficiency in pilot control circuits. The DNCADWN212 operates with a valve capacity based on port 3 as the inlet and port 1 as the tank. While it allows for reverse flow, optimum performance under this condition is not guaranteed. The robust design includes a solenoid tube assembly rated for fatigue at 5000 psi (350 bar), making it suitable for demanding applications. The valve requires no minimum hydraulic pressure for operation and incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. This model employs a wet armature design where the working fluid surrounds the armature. This exposure can lead to fluid degradation if the coil remains energized over extended periods. The DNCADWN212 offers various coil termination and voltage options, including designs with surge protection, and features a unique magnetic design that enhances solenoid efficiency and reliability in valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Connector options provide up to IP69K protection ratings, with additional weather-resistant coils available for enhanced environmental safeguarding. The construction of this valve uses Sun's floating style to reduce internal part binding risks due to installation torque or machining variations. Overall, the Sun Hydraulics DNCADWN212 offers robust performance and flexible configurations, making it an ideal choice for sophisticated hydraulic system applications requiring reliable directional control.

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.
