The Sun Hydraulics DMDADPN824 (DMDADPN824) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. As a direct-acting, balanced spool directional valve, it operates without requiring a minimum hydraulic pressure, enhancing its versatility in various applications. The valve features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for rigorous industrial uses. The DMDADPN824 is particularly noted for its closed transition spools (B and R), which do not allow flow between positions, thereby providing quicker and more consistent response times ideal for pilot control applications where capacity is less critical. This model incorporates EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. This model also benefits from a wet armature design where the working fluid surrounds the armature. While this setup helps in certain scenarios, it requires consideration of the fluid type used as some may degrade under prolonged exposure to heat. The interchangeable coils with other Sun Series 1 solenoid products add to the flexibility and ease of use of this valve. For manual override operations, the DMDADPN824 includes a detent mechanism designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles. It supports up to 12 gpm (45 L/min) capacity and has typical response times around 50 ms. Additionally, the floating style construction minimizes internal parts binding, ensuring reliable operation even under variable installation conditions. This makes the DMDADPN824 an efficient choice for dynamic systems requiring precise control and robust performance.
