The Sun Hydraulics DNCADZV71299 (DNCADZV71299) is a solenoid-operated, 4-way, 2-position cartridge valve that features a direct-acting, balanced spool with closed transition between positions. This design significantly minimizes oil loss during shifting, which is crucial in pilot control circuits. The valve operates efficiently with port 3 as the inlet and port 1 as the tank, although it does allow for reverse flow; however, optimal performance in reverse cannot be assured and is generally not recommended. With a fatigue rating of 5000 psi (350 bar), the solenoid tube assembly of this valve is robust and suitable for high-pressure applications. It requires no minimum hydraulic pressure to operate, making it versatile across various hydraulic systems. The valve's cartridges are available with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. This model also incorporates a wet armature design where the working fluid surrounds the armature. While this can lead to higher temperatures if the coil remains energized over extended periods, potentially affecting fluid integrity and cartridge function, it remains an efficient design choice for many applications. Moreover, the DNCADZV71299 offers various coil termination and voltage options including models with surge protection. Notably, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Connector options for these coils can achieve ratings up to IP69K for enhanced environmental protection. Additionally, this model uses Sun\u2019s floating style construction which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. Overall, the DNCADZV71299 is engineered for reliability and versatility with a maximum flow capacity of 8 gpm (30 L/min) and maximum operating pressure of 5000 psi (350 bar). Its rapid response time of approximately 50 ms and high switching frequency up to 15000 cycles per hour make it an optimal choice for dynamic systems requiring precise control and frequent operation.
