The Sun Hydraulics DMDADRN248 (DMDADRN248) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is engineered to operate effectively without requiring a minimum hydraulic pressure. It features a fatigue-rated solenoid tube assembly for services up to 5000 psi (350 bar), ensuring reliable performance under demanding conditions. The valve's construction includes spools B and R that remain closed during the transition between positions, which enhances performance at the cost of lower flow capacity. However, this feature allows for faster and more consistent response times when used as pilot controls where flow capacity is less critical. The manual override in models with D or L control is intended for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. Additionally, the DMDADRN248 incorporates EPDM seals suitable for systems using phosphate ester fluids while avoiding exposure to petroleum-based substances which could damage these seals. Its wet armature design means the working fluid surrounds the armature, potentially affecting fluid integrity if exposed to prolonged heat. Interchangeable coils with other Sun Series 1 solenoid products add versatility to this component, allowing mounting in either direction on the tube. The design also features Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a maximum operating pressure of 5000 psi (350 bar), a typical response time of 50 ms, and a flow capacity of 12 gpm (45 L/min). This makes the DMDADRN248 ideal for various high-pressure applications requiring precise control and reliability.
