The Sun Hydraulics DMDAMAN848 (DMDAMAN848) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it suitable for demanding applications. The valve's spools, B and R, are closed during the transition between two positions to enhance performance at the cost of capacity. This characteristic is particularly beneficial in pilot control applications where rapid and consistent response times are critical. The DMDAMAN848 operates without requiring a minimum hydraulic pressure, which allows for flexibility in various system designs. It includes options for manual override controls (D, L, T), each designed with a detent mechanism for temporary actuation and an expected mechanical life of approximately 7,000 cycles. The valve is compatible with EPDM seals when used in systems incorporating phosphate ester fluids; however, these seals must not be exposed to petroleum-based substances as they can cause damage. Further enhancing its utility, the DMDAMAN848 employs a wet armature design wherein the working fluid surrounds the armature. This design consideration is crucial when the coil remains energized over extended periods, as some fluids may degrade under prolonged exposure to heat. Additionally, this model's coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The construction of the DMDAMAN848 incorporates Sun\u2019s floating style to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum flow capacity of 12 gpm (45 L/min) and swift response times typically around 50 ms, this valve ensures efficient operation under high switching frequencies up to 15,000 cycles per hour. The compact design includes manual override features requiring minimal force and stroke for activation, making it user-friendly and reliable for various hydraulic applications.
