The Sun Hydraulics DNDATSN536 (DNDATSN536) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting and balanced spool directional control. Engineered for a robust service life, its solenoid tube assembly is fatigue-rated to handle pressures up to 5000 psi (350 bar). This valve operates without requiring any minimum hydraulic pressure, making it versatile across various applications. Users can select from multiple manual override options, although it should be noted that weatherized coils are incompatible with these overrides. The D and L control models feature a detent mechanism intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. This cartridge valve is equipped with EPDM seals suitable for systems utilizing phosphate ester fluids; however, exposure to petroleum-based substances can damage these seals. Utilizing a wet armature design, the working fluid envelops the armature and absorbs heat from the coil\u2014a consideration when the coil remains energized over extended periods. This design may influence performance in fluids like water-glycol mixtures that degrade under such conditions. A variety of coil termination and voltage options are available, including those with surge protection features. The solenoid's innovative magnetic design provides high efficiency by delivering substantial spool actuating force per watt consumed, ensuring reliable valve shifting. Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Connector options offer protection ratings up to IP69K for enhanced environmental resilience. The valve's construction incorporates Sun\u2019s floating style design to minimize internal part binding due to excessive installation torque or machining variations in cavity/cartridge interfaces. With a capacity of 10 gpm (40 L/min), this valve features a typical response time of 50 ms and supports a switching frequency of up to 15,000 cycles per hour. It requires specific manual override force and stroke parameters and has precise installation torque specifications for optimal performance.
