The Sun Hydraulics DMDALNV924N (DMDALNV924N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve featuring a direct-acting, balanced spool design. This valve is particularly noted for its robust construction that includes a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). It is designed with closed transitions between Spools B and R, which enhances performance by providing faster and more consistent response times during the operation. This makes it ideal for applications requiring precise control such as in pilot controls where capacity is less critical. The DMDALNV924N operates without the need for minimum hydraulic pressure, enabling reliable functionality across a wide range of operating conditions. The manual override feature incorporated in models with D or L control uses a detent mechanism designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. Additionally, this model can be equipped with EPDM seals suitable for phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could be damaged. This valve also employs a wet armature design where the working fluid surrounds the armature. While this aids in cooling when the coil is energized, it requires careful consideration of fluid type to avoid breakdown and potential varnishing which could impair cartridge function over time. The interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing customization according to specific system requirements. Key specifications include a flow capacity of 12 gpm (45 L/min), rapid response times typically around 50 ms, and maximum operational leakage well controlled at 5 in\u00b3/min at 3000 psi. The valve's compact dimensions and floating style construction minimize internal parts binding and ensure smooth operation even under varied installation conditions.
