The Sun Hydraulics DMDAXPV71299 (DMDAXPV71299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic control in various applications. This direct-acting, balanced spool directional valve is uniquely engineered to operate without minimum hydraulic pressure, enhancing its versatility across different system conditions. It features a fatigue-rated solenoid tube assembly for pressures up to 5000 psi (350 bar), ensuring reliability and longevity under demanding operational circumstances. The DMDAXPV71299 valve incorporates closed transitions between spool positions B and R, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The wet armature design of the valve allows the working fluid to surround the armature, which is beneficial for heat dissipation but requires consideration regarding fluid compatibility, especially with water-glycol mixtures that may degrade at higher temperatures. For manual override operations, this model includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of about 7,000 cycles. It supports interchangeable coils with other Sun Series 1 solenoid products and features a floating style construction that minimizes internal parts binding due to installation torque or machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure capability of 5000 psi (350 bar). The valve also offers minimal leakage and is capable of handling switching frequencies up to 15,000 cycles per hour. These characteristics make the DMDAXPV71299 an efficient solution for advanced hydraulic systems requiring precise control and high reliability.
