The Sun Hydraulics DMDALAV (DMDALAV) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. It features a direct-acting, balanced spool directional control that ensures precise operation with no minimum hydraulic pressure required for activation. The valve is particularly noted for its robust construction including a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). This model is designed with closed transitions between Spools B and R, optimizing performance by enabling faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The manual override option, available in models equipped with the D or L control, includes a detent mechanism intended for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. The DMDALAV valve utilizes EPDM seals specifically for systems using phosphate ester fluids; however, these seals are vulnerable to damage when exposed to petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature which can be a consideration if the coil remains energized over extended periods as some fluids may degrade under heat. Additional versatility comes from interchangeable coils compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This model also incorporates Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at 110 SUS (24 cSt) being limited to 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The manual override requires a force of about 5 lbs at 1000 psi per port. This compact yet powerful hydraulic solution weighs approximately 0.60 lb (0.30 kg), ensuring both efficiency and reliability in various hydraulic applications.
