The Sun Hydraulics DMDALPV71299 (DMDALPV71299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve integrates advanced features such as a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for rigorous applications. The valve's design ensures that spools B and R are closed during the transition between positions, enhancing performance by providing faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. Engineered for durability and reliability, the DMDALPV71299 features a manual override with a detent mechanism intended for temporary actuation, boasting a mechanical life expectancy of approximately 7,000 cycles. It is equipped with EPDM seals specifically chosen for compatibility with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The wet armature design of the valve means that the working fluid surrounds the armature which could be subjected to heat if the coil remains energized over extended periods. This model is versatile with its interchangeable coils that can be mounted on the tube in either direction and shares compatibility with other Sun Series 1 solenoid products. The construction includes Sun's floating style to minimize internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a flow capacity of up to 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve is an efficient solution for managing directional control in hydraulic systems while ensuring minimal leakage and high switching frequency capabilities.
