The Sun Hydraulics DMDALNV2E12V (DMDALNV2E12V) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for demanding environments. The valve\u2019s spools (B and R) maintain a closed position during the transition between two positions to enhance performance limits at reduced capacities, which is particularly beneficial in pilot control applications where speed and consistency are critical. This model does not require a minimum hydraulic pressure to operate, thanks to its direct actuation design. It includes manual override options with a detent mechanism intended for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. The DMDALNV2E12V is equipped with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Another feature of this valve is its wet armature design that allows the working fluid to surround the armature, potentially affecting fluid integrity under prolonged energization due to heat exposure. Interchangeable coils with other Sun Series 1 solenoid products add versatility in maintenance and replacement processes. The construction incorporates Sun\u2019s floating style design that minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With specifications like a maximum flow capacity of 12 gpm (45 L/min), rapid typical response times of 50 ms, and switching frequency capabilities up to 15,000 cycles per hour, the DMDALNV2E12V is engineered for both reliability and precision in various hydraulic applications.
