The Sun Hydraulics DNDAXDN2E12V (DNDAXDN2E12V) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered to withstand fatigue with a solenoid tube assembly rated for service up to 5000 psi (350 bar). It operates without requiring a minimum hydraulic pressure, making it versatile for various hydraulic applications. The DNDAXDN2E12V offers multiple manual override options, though it is important to note that manual override features are not compatible with weatherized coils. For models equipped with the D or L control, the manual override's detent mechanism is intended for temporary actuation with an approximate mechanical life of 7,000 cycles. This valve is suitable for systems utilizing phosphate ester fluids when equipped with EPDM seals; however, exposure to petroleum-based fluids can damage these seals. The wet armature design allows working fluid to surround the armature and absorb heat generated by the coil, which may impact performance over prolonged periods of coil energization. A variety of coil termination and voltage configurations are available, including options with surge protection. The high-efficiency solenoid design delivers significant spool actuating force per watt consumed, enhancing reliability in valve shifting operations. Coil connectors offer ratings up to IP69K for robust environmental protection. Additionally, this model incorporates Sun's floating style construction to reduce internal part binding risks due to installation torque or machining variations. Key specifications include a cavity size of T31A, Series 1 capacity at 10 gpm (40 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum leakage at 110 SUS (24 cSt) limited to 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). The DNDAXDN2E12V supports a switching frequency of up to 15,000 cycles per hour and requires specific manual override force and stroke parameters for operation.
