The Sun Hydraulics DMDALRV612 (DMDALRV612) is a solenoid-operated 3-way, 2-position cartridge valve that excels in high-performance applications. This direct-acting, balanced spool directional valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar), making it suitable for rigorous hydraulic tasks. The valve features spools B and R which are closed during the transition between two positions to enhance performance limits at the cost of lower capacity. This attribute makes it ideal for use as pilot controls where capacity is less critical but fast and consistent response times are essential. The DMDALRV612 operates without requiring a minimum hydraulic pressure, adding to its versatility in various system configurations. It includes manual override options with a detent mechanism designed for temporary actuation, boasting a mechanical life expectancy of approximately 7,000 cycles. The valve's compatibility with EPDM seals makes it suitable for systems using phosphate ester fluids while cautioning against exposure to petroleum-based fluids which could damage the seals. Additionally, the wet armature design of the valve ensures that the working fluid surrounds the armature, potentially affecting performance if the coil remains energized over extended periods due to heat exposure. It supports interchangeable coils with other Sun Series 1 solenoid products and can be mounted on the tube in either direction. The design incorporates Sun's floating style construction to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum leakage at 110 SUS (24 cSt) being limited to 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The switching frequency capability reaches up to 15,000 cycles/hr, ensuring robust performance for demanding applications.
