The Sun Hydraulics DNDAMZV648 (DNDAMZV648) is a solenoid-operated, 4-way, 2-position cartridge valve designed for efficient directional control in hydraulic systems. This direct-acting, balanced spool valve operates without the need for minimum hydraulic pressure, making it versatile for various applications. It features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), ensuring durability and reliability under high-stress conditions. The valve incorporates a wet armature design that allows the working fluid to cool the armature, although prolonged coil energization may affect certain fluids like water-glycol mixtures. The DNDAMZV648 offers several manual override options; however, manual overrides are not compatible with weatherized coils. The D or L control-equipped models include a detent mechanism intended for temporary actuation, with an estimated mechanical life expectancy of approximately 7,000 cycles. Seals made from EPDM are available for systems utilizing phosphate ester fluids but should be avoided in petroleum-based environments due to potential damage. This cartridge valve is built with Sun's floating style construction to reduce binding risks from installation torque or machining variations. It boasts a high-efficiency solenoid design that delivers strong spool actuating force per watt expended, ensuring reliable operation. The valve supports various coil termination and voltage options, some offering surge protection and IP69K rating for enhanced environmental resistance. Coils from other Sun Series 1 solenoid products are interchangeable and can be mounted in either direction on this model. With a capacity of 10 gpm (40 L/min) and typical response time of 50 ms, the DNDAMZV648 is suitable for applications demanding rapid switching frequencies up to 15,000 cycles per hour. It requires minimal manual override force and features manageable installation specifications such as a .75-inch solenoid tube diameter and .60 lb model weight.
