The Sun Hydraulics DMDADNV728 (DMDADNV728) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features a robust design with spools B and R closed in transition, which enhances performance by providing faster and more consistent response times, particularly suitable for applications requiring precise control such as pilot controls where capacity is less critical. The valve incorporates a wet armature design, where the working fluid surrounds the armature. This design is crucial for its operation but requires consideration of the fluid type used; for instance, EPDM seals in this model are compatible with phosphate ester fluids but not with petroleum-based fluids. The valve's solenoid coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction for added flexibility in installation. Additionally, the DMDADNV728 features a manual override with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy of approximately 7,000 cycles. The manual override requires minimal force and provides quick actuation capabilities. With its floating style construction, the valve minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. This model is ideal for applications requiring reliable switching capabilities and precise hydraulic control under high-pressure conditions. Its rapid response time and high switching frequency make it well-suited for dynamic systems needing consistent operational performance.
