The Sun Hydraulics DMDAMBN71299 (DMDAMBN71299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precision hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and capability to handle a maximum operating pressure of 5000 psi (350 bar), making it suitable for demanding applications. It boasts a typical response time of 50 ms and features spools B and R that are closed in the transition between their two positions, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The DMDAMBN71299 operates without requiring a minimum hydraulic pressure, facilitating reliable performance across various conditions. The manual override feature incorporated in models with D or L control uses a detent mechanism designed primarily for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. Additionally, this model can accommodate EPDM seals suitable for phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. This valve employs a wet armature design where the working fluid surrounds the armature\u2014important to consider as prolonged coil energization could lead to fluid breakdown in certain conditions. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model. Furthermore, the floating style construction minimizes internal parts binding that could result from excessive installation torque or cavity/cartridge machining variations. With a flow capacity of up to 12 gpm (45 L/min) and minimal leakage at high pressures (5 in\u00b3/min at 3000 psi), the DMDAMBN71299 is engineered for efficiency and reliability in hydraulic circuit operations requiring precise control and rapid switching capabilities.
