The Sun Hydraulics DMDAXAN528 (DMDAXAN528) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is notable for its fatigue rating for 5000 psi (350 bar) service, making it suitable for demanding applications. The valve features closed transitions between Spools B and R to enhance performance limits while sacrificing some capacity, which is beneficial in pilot control applications where capacity is less critical. With a response time of approximately 50 ms and a maximum operating pressure of 5000 psi (350 bar), the DMDAXAN528 ensures quick and reliable operation in various hydraulic setups. It has a flow capacity of up to 12 gpm (45 L/min) and can handle switching frequencies up to 15,000 cycles per hour. The manual override feature requires minimal force, with specific requirements of 5 lbs at 1000 psi for Port 1. This model incorporates Sun Hydraulics' floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. The solenoid tube assembly\u2019s wet armature design means that the working fluid surrounds the armature; this design consideration is crucial when using fluids that degrade at high temperatures like water-glycol mixtures. Designed for versatility, the DMDAXAN528\u2019s coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. For systems using phosphate ester fluids, cartridges configured with EPDM seals are recommended as exposure to petroleum-based fluids can damage these seals. This model also supports easy maintenance with available seal kits specified for different components ensuring long-term reliability and performance.
