The Sun Hydraulics DNCADXN4E12V (DNCADXN4E12V) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve features a closed transition between positions, minimizing oil loss during shifting which is crucial in pilot control circuits. The valve operates efficiently with a capacity of 8 gpm/30 L/min based on port 3 as the inlet and port 1 as the tank, although reverse flow is possible but not recommended for optimal performance. Constructed to handle a maximum operating pressure of 5000 psi (350 bar), the DNCADXN4E12V is fatigue rated for demanding applications. It does not require minimum hydraulic pressure for operation, making it versatile and reliable across various operational conditions. The valve's solenoid tube assembly is engineered to withstand continuous use, being rated up to IP69K depending on the coil connector options chosen. These connectors are designed to offer robust environmental protection against harsh conditions. Additionally, this model incorporates Sun's floating style construction which reduces risks of internal parts binding due to installation stresses or cavity/cartridge machining variations. With quick response times typically around 50 ms and capable of handling up to 15000 switching cycles per hour, this valve ensures responsive and durable performance in intensive use scenarios. The DNCADXN4E12V also allows for manual override with minimal force requirement, adding an extra layer of operational security and manual control when needed. This Sun Hydraulics model supports a variety of coil termination and voltage options including configurations with surge protection, enhancing its adaptability for different system requirements and extending its application range across multiple hydraulic system designs.

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.
