The Sun Hydraulics DMDAXAN536 (DMDAXAN536) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for use in hydraulic systems where precise control of fluid direction is required. The valve features a fatigue-rated solenoid tube assembly suitable for service up to 5000 psi (350 bar), making it robust for high-pressure applications. It operates with a closed transition between positions B and R, enhancing performance by providing faster and more consistent response times\u2014ideal for pilot control applications where capacity is less critical. The DMDAXAN536 requires no minimum hydraulic pressure to function due to its direct actuation design. For temporary manual actuation, models with D or L control include a detent mechanism in the manual override. The mechanical life expectancy of the manual control assembly (D, L, and T types) is about 7,000 cycles. This model is compatible with EPDM seals for systems using phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. Additionally, the valve employs a wet armature design allowing the working fluid to surround the armature which may affect fluid integrity during prolonged energization due to heat exposure. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in mounting and maintenance. The valve also incorporates Sun's floating style construction which minimizes 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 time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). It supports a switching frequency up to 15000 cycles/hr and has minimal leakage at high pressures. This compact yet robust component weighs just 0.60 lb (0.30 kg), ensuring it can be integrated into various system configurations without significant weight implications.
