The Sun Hydraulics DMDALPN836 (DMDALPN836) 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 notable for its closed transition spools (B and R), which remain closed during the shift from one position to another, enhancing performance by offering faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. Constructed to handle a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min), the DMDALPN836 is equipped to deliver efficient hydraulic control with minimal leakage\u2014rated at just 5 in\u00b3/min at 3000 psi. It features a solenoid tube assembly that is fatigue-rated for high-pressure service, ensuring durability and reliability even under strenuous conditions. This valve also incorporates manual override options with detent mechanisms designated for temporary actuation, supporting up to approximately 7,000 cycles. The manual override requires a force of about 5 lbs at 1000 psi per port. Furthermore, the wet armature design of the DMDALPN836 means that the working fluid surrounds the armature; while this aids in cooling, it requires careful consideration of fluid type as certain fluids may degrade under prolonged exposure to heat. For compatibility with different hydraulic fluids, cartridges configured with EPDM seals are specifically designed for systems using phosphate ester fluids. However, these seals are susceptible to damage when exposed to petroleum-based fluids. Interchangeability with other Sun Series 1 solenoid products adds versatility in use and maintenance. The valve's robust design includes features like Sun's floating style construction which minimizes internal part binding due to installation torque or cavity/cartridge machining variations. With a compact model weight of only .60 lb (0.30 kg), the DMDALPN836 offers an effective solution for dynamic hydraulic system needs across various applications.
