The Sun Hydraulics DNDATYN512 (DNDATYN512) 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 applications with a fatigue rating suitable for up to 5000 psi (350 bar) service. It operates without requiring minimum hydraulic pressure and offers various manual override options, including configurations without a manual override. Notably, models with the D or L controls feature a detent mechanism intended for temporary actuation, boasting a mechanical life expectancy of approximately 7,000 cycles. The valve is compatible with EPDM seals for systems using phosphate ester fluids but should avoid petroleum-based fluids to prevent seal damage. The DNDATYN512 utilizes a wet armature design where the working fluid surrounds the armature, potentially impacting performance if the coil remains energized over extended periods. This aspect is particularly relevant when using water-glycol mixtures that may degrade over time due to heat exposure. The solenoid offers high efficiency through its unique magnetic design, providing substantial spool actuating force per watt consumed and ensuring reliable valve operation. This model accommodates various coil termination and voltage options, some equipped with surge protection. Coils are interchangeable within Sun Series 1 solenoid products and can be mounted bidirectionally on the tube. For enhanced environmental protection, weatherized coils and kits are available. The valve\u2019s construction incorporates Sun\u2019s floating style design to reduce internal binding risks from excessive installation torque or machining variations. Key specifications include a flow capacity of 10 gpm (40 L/min), response time of approximately 50 ms, maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), and switching frequency up to 15,000 cycles per hour. The valve features a T31A cavity configuration with an installation torque range between 30-35 lbf-ft (41-47 Nm).
