The Sun Hydraulics DNCADXV812N (DNCADXV812N) 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 ensures smooth and efficient operation with its closed transition between positions, significantly minimizing oil loss during shifting\u2014a crucial feature for maintaining system integrity, particularly in pilot control circuits. Engineered for robust performance, the DNCADXV812N can handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 8 gpm (30 L/min), making it suitable for a variety of demanding applications. The valve's solenoid tube assembly is fatigue rated for high-pressure service, ensuring durability and long service life even under strenuous conditions. Additionally, the valve operates without requiring a minimum hydraulic pressure, enhancing its versatility across different hydraulic setups. This model incorporates EPDM seals specifically designed for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. The wet armature design of the solenoid means that it is immersed in the working fluid which helps in heat management but also requires consideration regarding the type of fluid used due to potential breakdowns at elevated temperatures. Sun Hydraulics has equipped the DNCADXV812N with various coil termination and voltage options to suit different operational requirements and environments. Coils are interchangeable with other Sun Series 1 products and can be installed in either direction on the tube. For environmental resilience, additional weatherized coils and kits are available. The DNCADXV812N also features Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining\u2014this ensures consistent performance and reliability. With its advanced design and flexible configuration options, this valve is an excellent choice for sophisticated hydraulic systems needing precise control and reliability.

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.
