The Sun Hydraulics DNDATDV724 (DNDATDV724) is a solenoid-operated 4-way, 2-position cartridge valve designed for precision and durability. This direct-acting, balanced spool directional valve does not require minimum hydraulic pressure for operation, making it versatile for various applications. The solenoid tube assembly is fatigue-rated for service pressures up to 5000 psi (350 bar), ensuring reliability under high-pressure conditions. It features several manual override options, though it's important to note that manual overrides are not compatible with weatherized coils. The D, L, and T manual control assemblies offer a mechanical life expectancy of approximately 7,000 cycles and are intended for temporary actuation. This valve employs a wet armature design where the working fluid surrounds the armature, which can be influenced by heat from the coil during prolonged energization. This design consideration is crucial when using fluids like water-glycol mixtures that may degrade under such conditions. The high-efficiency solenoid offers significant spool actuating force per watt consumed, promoting dependable valve shifting. The DNDATDV724 accommodates a variety of coil termination and voltage options with interchangeable coils compatible with other Sun Series 1 products. Coil connectors provide ratings up to IP69K for enhanced environmental protection. The valve's construction incorporates Sun's floating style to minimize internal binding from installation torque or machining variations. Technical specifications include a cavity size of T31A, a capacity of 10 gpm (40 L/min), response time typically around 50 ms, and maximum leakage at specified viscosity of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar). Manual override requires a force of approximately 5 lbs/1000 psi and offers a stroke length of .10 inches (2.5 mm). This model weighs .60 lb (.30 kg) with installation torque between 30 - 35 lbf ft (41 - 47 Nm). Seal kits are available with Viton materials for both cartridge and coil components.
