The Sun Hydraulics DMDADAV72499 (DMDADAV72499) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve specifically designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve is engineered to operate effectively without minimum hydraulic pressure, enhancing its versatility across various operational scenarios. The valve features a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure applications. The design incorporates closed transitions between spools B and R, optimizing performance by allowing faster and more consistent response times, especially useful in pilot control setups where capacity is less critical. The mechanical life expectancy of the manual override mechanism in models with the D or L control is approximately 7,000 cycles, indicating reliable long-term usage. For systems utilizing phosphate ester fluids, cartridges with EPDM seals are recommended to prevent damage from petroleum-based substances. The wet armature design aids in maintaining fluid contact around the armature which helps manage heat during prolonged coil energization; however, this could affect fluid integrity over time due to potential breakdowns when using water-glycol mixtures. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products, which can be mounted in either direction on the tube. The construction employs Sun\u2019s floating style to minimize internal part binding caused by excessive installation torque or machining variations of cavity/cartridge. With a maximum flow capacity of 12 gpm (45 L/min) and a swift typical response time of 50 ms, this valve ensures efficient operation under varying conditions. It supports a maximum operating pressure of 5000 psi (350 bar) and demonstrates minimal leakage at high pressures.
