The Sun Hydraulics DMDAXAN828 (DMDAXAN828) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for hydraulic systems. This direct-acting, balanced spool directional valve features a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring durability and reliability even under demanding conditions. The valve operates with no minimum hydraulic pressure required, facilitating consistent operation across a range of applications. The DMDAXAN828 includes unique design features such as closed transitions between spool positions B and R, which enhance performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. It's equipped with EPDM seals suitable for use with phosphate ester fluids, although these seals must avoid exposure to petroleum-based products to prevent damage. This model also boasts a wet armature design allowing the working fluid to surround the armature which helps manage heat during prolonged coil energization but requires careful consideration of fluid type to avoid breakdown and varnish formation. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility, while the floating style construction minimizes internal parts binding caused by installation torque or cavity/cartridge machining variations. Key specifications include a maximum operating pressure of 5000 psi, flow capacity of 12 gpm (45 L/min), and typical response time of 50 ms. The manual override feature requires minimal force and provides a stroke length suitable for temporary actuation. With its robust construction and thoughtful engineering, the Sun Hydraulics DMDAXAN828 valve offers an effective solution for controlling directional flow in hydraulic systems efficiently and reliably.
