The Sun Hydraulics DMDAXBV712N (DMDAXBV712N) is a solenoid-operated 3-way, 2-position cartridge valve that excels in delivering precise directional control in hydraulic systems. This direct-acting, balanced spool valve is designed to operate efficiently with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). Its robust construction includes a fatigue-rated solenoid tube assembly suitable for high-pressure service, ensuring reliable performance under demanding conditions. The valve features closed transitions between its two positions, spools B and R, which enhances performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The integration of EPDM seals makes this model suitable for use with phosphate ester fluids, although it should not be exposed to petroleum-based fluids which could damage the seals. A distinctive feature of the DMDAXBV712N is its wet armature design; the working fluid surrounds the armature which helps manage the heat generated by the coil. This design consideration is crucial for applications where the coil remains energized over extended periods. Additionally, the manual override option included in models with D or L control uses a detent mechanism designed primarily for temporary actuation, supporting about 7,000 cycles. This valve also boasts interchangeable coils compatible with other Sun Series 1 solenoid products and incorporates Sun's floating style construction which minimizes internal parts binding due to installation or machining variations. With a typical response time of 50 ms and capable of handling up to 15,000 switching cycles per hour, the DMDAXBV712N is well-suited for applications requiring high switching frequency and precision fluid control.
