The Sun Hydraulics DMDALPV299 (DMDALPV299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is built to handle a maximum operating pressure of 5000 psi (350 bar) and is fatigue rated for the same, ensuring durability and reliability under high-pressure operations. The valve features closed transitions between positions B and R, optimizing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is not a critical factor. This model incorporates a wet armature design where the working fluid surrounds the armature. While this design aids in efficient operation, it requires consideration of the fluid type used; specifically, it is compatible with EPDM seals for phosphate ester fluids but not with petroleum-based fluids which can degrade the seals. The DMDALPV299 supports a flow capacity up to 12 gpm (45 L/min) and offers quick response times typically around 50 ms. Interchangeable coils from Sun\u2019s Series 1 solenoid products enhance this model's versatility, allowing for easy maintenance and replacement. Additionally, the valve features Sun\u2019s floating style construction which minimizes internal parts binding that could result from excessive installation torque or cavity/cartridge machining variations. The manual override option present in models equipped with D or L control uses a detent mechanism intended for temporary actuation only, with a mechanical life expectancy of about 7,000 cycles. Optimal for applications requiring robust control in hydraulic systems, this valve ensures efficient operation with minimal leakage (maximum 5 in\u00b3/min at 3000 psi) and supports high switching frequencies up to 15,000 cycles per hour. This makes it an ideal choice for systems requiring frequent and precise changes in direction of flow under varying pressure conditions.
