The Sun Hydraulics DMDAXBV648 (DMDAXBV648) is a solenoid-operated 3-way, 2-position cartridge that functions as a direct-acting, balanced spool directional valve. This model features a robust design with a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring durability and reliability under high-pressure conditions. The valve is designed with closed transitions between Spools B and R, enhancing performance by offering faster and more consistent response times, particularly useful when employed as pilot controls. The DMDAXBV648 operates without requiring a minimum hydraulic pressure, facilitating its use in various applications. It includes optional manual override controls (D, L, T types), which are primarily intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. This model also employs EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. Another significant feature of this valve is its wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil remains energized for extended periods, potentially affecting fluid integrity in certain conditions. The valve supports a flow capacity of up to 12 gpm (45 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). Its quick response time of approximately 50 ms and a switching frequency of up to 15,000 cycles/hr make it an efficient choice for dynamic systems. Additionally, the DMDAXBV648 features interchangeable coils with other Sun Series 1 solenoid products and incorporates Sun's floating style construction to minimize internal parts binding due to installation torque or machining variations. This model's adaptability and robust specifications make it suitable for demanding directional control applications where precision and reliability are critical.
