The Sun Hydraulics DNDAXEV (Material Number: DNDAXEV) is a solenoid-operated 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered for high performance with a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), ensuring reliable operation under demanding conditions. It requires no minimum hydraulic pressure for activation, making it versatile across various applications. The valve offers multiple manual override options, although manual override features are not compatible with weatherized coils. The manual control assemblies equipped with D or L controls feature a detent mechanism intended for temporary actuation and have a mechanical life expectancy of approximately 7,000 cycles. The DNDAXEV model utilizes EPDM seals suitable for systems using phosphate ester fluids, while exposure to petroleum-based fluids can damage these seals. It employs a wet armature design where the working fluid surrounds the armature, potentially affecting function if the coil is energized for extended periods due to heat generation. A variety of coil termination and voltage options are available, including those with surge protection features. The solenoid's magnetic design ensures high efficiency by providing substantial spool actuating force per watt consumed. Interchangeable with other Sun Series 1 solenoid products, the coils can be mounted in either direction on the tube and offer connector options rated up to IP69K for enhanced environmental protection. The cartridge incorporates Sun's floating style construction to reduce internal part binding risks due to excessive installation torque or machining variations in cavity/cartridge setups. With a capacity of 10 gpm (40 L/min) and maximum leakage at specified viscosity levels of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), this model supports switching frequencies up to 15,000 cycles per hour and provides reliable performance across diverse applications.
