The Sun Hydraulics DMDALAN712 (DMDALAN712) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control in various applications. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, making it highly versatile and effective in diverse operating conditions. The valve features a fatigue rating for 5000 psi (350 bar) service, ensuring its durability and reliability under high-pressure scenarios. With its unique design, the spools B and R remain closed during the transition between two positions to enhance performance limits at the cost of reduced capacity. However, this characteristic is advantageous in pilot control applications where capacity is less critical but faster and more consistent response times are essential. The DMDALAN712 incorporates EPDM seals suitable for systems using phosphate ester fluids, although these seals are vulnerable to damage when exposed to petroleum-based fluids. This model also boasts a wet armature design where the working fluid surrounds the armature, potentially affecting performance if the coil remains energized over extended periods due to heat exposure. It supports a maximum flow capacity of 12 gpm (45 L/min) and can handle up to 5000 psi (350 bar) of operating pressure. The manual override feature requires minimal force and includes a detent mechanism designed primarily for temporary actuation with an estimated mechanical life of about 7,000 cycles. Interchangeable with other Sun Series 1 solenoid products, the coils can be mounted in either direction on the tube. This flexibility is complemented by Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. These features make the Sun Hydraulics DMDALAN712 an excellent choice for sophisticated hydraulic systems requiring robust control and reliable operation.
