The Sun Hydraulics DMDALRV924N (DMDALRV924N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. The valve features a direct-acting, balanced spool directional mechanism that ensures reliable operation without the need for minimum hydraulic pressure. It is equipped with spools B and R, which are closed during the transition between positions to deliver a more consistent response, particularly suitable for pilot control applications where capacity is less critical. This model boasts a robust construction with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The manual override feature incorporates a detent mechanism designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles. Notably, the valve uses EPDM seals intended specifically for systems utilizing phosphate ester fluids; these seals are not compatible with petroleum-based fluids as exposure can lead to damage. Another key feature of the DMDALRV924N is its wet armature design which allows the working fluid to surround the armature and manage heat during prolonged coil energization. This design consideration is crucial when using certain fluids like water-glycol mixtures that may degrade under high temperatures. Additionally, the valve supports interchangeable coils from other Sun Series 1 solenoid products and features Sun\u2019s floating style construction to minimize internal parts binding due to installation torque or machining variations. With a maximum operating pressure of 5000 psi and a flow capacity of up to 12 gpm (45 L/min), this valve is engineered to handle substantial hydraulic loads efficiently. Its switching frequency can reach up to 15,000 cycles per hour, and it has been optimized for fast response times typically around 50 ms. These specifications make the DMDALRV924N an excellent choice for advanced hydraulic systems requiring dependable performance and rapid switching capabilities.
