The Sun Hydraulics DNCADXV812 (DNCADXV812) 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 valve ensures smooth and efficient operation with its closed transition between positions, which significantly minimizes oil loss during shifting\u2014a critical feature in pilot control circuits. The valve\u2019s design allows for port 3 to serve as the inlet and port 1 as the tank, although it supports reverse flow with a caution on potentially reduced performance. Engineered for durability and reliability, the DNCADXV812 features a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it suitable for rigorous applications. It does not require a minimum hydraulic pressure to operate, which enhances its versatility across different hydraulic systems. The valve is equipped with EPDM seals specifically designed for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. This model also incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is important when the coil is energized for prolonged periods since some fluids may degrade under high temperatures. Additionally, Sun Hydraulics offers a variety of coil termination and voltage options for this model, including configurations with surge protection to meet diverse operational requirements. The DNCADXV812\u2019s magnetic design of the solenoid yields high efficiency and robust spool actuating force per watt expended, ensuring reliable valve shifting even under challenging conditions. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Various coil connector options are available that provide up to IP69K rating for enhanced environmental protection against elements such as dust and water ingress. Moreover, this model benefits from Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This feature contributes significantly to the overall reliability and longevity of the valve in demanding operational environments.
