The Sun Hydraulics DNCADJV71219 (DNCADJV71219) is a high-performance, solenoid-operated, 4-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool valve ensures a closed transition between positions, minimizing oil loss during shifting which is essential in pilot control circuits. The DNCADJV71219 operates with a valve capacity based on port 3 as the inlet and port 1 as the tank, with reverse flow possible but not recommended for optimal performance. Engineered for robustness, the solenoid tube assembly of this model is fatigue rated for up to 5000 psi or 350 bar service. Its direct actuation requires no minimum hydraulic pressure to operate effectively. The valve features EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. The DNCADJV71219 incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization of the coil could lead to fluid degradation at high temperatures. Additionally, it offers a variety of coil termination and voltage options, including models with surge protection and weatherized coils for enhanced environmental protection. Notably efficient in its magnetic design, the solenoid provides high spool actuating force per watt expended which facilitates reliable valve shifting. The coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Options for coil connectors are rated up to IP69K for significant durability against environmental factors. This model also benefits from Sun's floating style construction which reduces internal part binding risks due to excessive installation torque or variations in cavity/cartridge machining. With a rapid response time and capable of handling high switching frequencies without performance degradation, the DNCADJV71219 is an excellent solution for demanding hydraulic applications requiring precise control and reliability.
