The Sun Hydraulics DNCADCN71299 (DNCADCN71299) is a solenoid-operated, 4-way, 2-position cartridge valve designed for efficient and reliable hydraulic control. This direct-acting, balanced spool directional valve features a closed transition between positions, which minimizes oil loss during shifting\u2014a crucial factor in maintaining the efficiency of pilot control circuits. The valve operates with a capacity based on port 3 as the inlet and port 1 as the tank, and while reverse flow is possible, it is not recommended due to potential performance variations. Constructed to endure demanding conditions, the solenoid tube assembly of this valve is fatigue rated for service up to 5000 psi (350 bar). It requires no minimum hydraulic pressure for operation, ensuring consistent performance across various applications. The DNCADCN71299 uses EPDM seals specifically suited for systems with phosphate ester fluids; however, these seals are vulnerable to damage if exposed to petroleum-based fluids. This model incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is vital when the coil is energized for extended periods since some fluids may degrade under prolonged exposure to heat. The DNCADCN71299 offers a variety of coil termination and voltage options, including configurations with surge protection. Its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Further enhancing its robustness, this valve features Sun's floating style construction which helps prevent internal parts from binding due to excessive installation torque or cavity/cartridge machining variations. With options for environmental protection through weatherized coils and kits, along with a high switching frequency of 15,000 cycles per hour and rapid response time typical at 50 ms, this model ensures reliable operation and longevity in various hydraulic applications.
