The Sun Hydraulics DNDATUN614 (DNDATUN614) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. Engineered for high performance, this valve operates efficiently without requiring a minimum hydraulic pressure. The solenoid tube assembly is fatigue-rated for service up to 5000 psi (350 bar), ensuring durability in demanding applications. Featuring various manual override options, the valve can be configured to meet specific operational needs; however, note that weatherized coils are not compatible with manual overrides. For models with D or L control, the detent mechanism allows temporary actuation with an expected mechanical life of approximately 7,000 cycles. This cartridge is suitable for systems using phosphate ester fluids when equipped with EPDM seals but should avoid petroleum-based substances to prevent seal damage. Utilizing a wet armature design enhances heat dissipation from the coil but requires consideration of fluid breakdown in long-term energized states\u2014particularly with water-glycol mixtures that may form varnishes over time. The DNDATUN614 offers a wide range of coil termination and voltage configurations, some featuring surge protection and high-efficiency magnetic design for reliable shifting. Coils are interchangeable within the Sun Series 1 solenoid products and can be mounted bi-directionally on the tube. With options reaching IP69K ratings, coil connectors provide robust environmental protection. Incorporating Sun's floating style construction minimizes internal binding risks due to installation torque or machining variations. With a capacity of 10 gpm (40 L/min) and response time typically at 50 ms, this valve supports switching frequencies up to 15,000 cycles per hour while maintaining minimal leakage rates under specified conditions. The valve's compact dimensions include a hex size of .78 inches (22.2 mm) and installation torque between 30-35 lbf-ft (41-47 Nm), with an overall weight of .60 lb (0.30 kg).
