The Sun Hydraulics DMDAXRV714 (DMDAXRV714) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient hydraulic control. This direct-acting, balanced spool directional valve features a fatigue rating for service at pressures up to 5000 psi (350 bar), making it suitable for high-pressure applications. The spool transitions between positions B and R are closed, enhancing performance by providing faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. This valve operates without the need for minimum hydraulic pressure, allowing for versatile usage across various hydraulic systems. The manual override options available with the D or L control are designed primarily for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. For environments using phosphate ester fluids, cartridges equipped with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as they can degrade the seals. The wet armature design of the DMDAXRV714 ensures that the working fluid envelops the armature which could be a consideration if the coil remains energized over extended periods due to potential breakdowns in certain fluids like water-glycol mixtures. Interchangeability of coils with other Sun Series 1 solenoid products adds to its flexibility in system design. Additionally, Sun\u2019s floating style construction is incorporated to minimize internal parts binding caused by excessive installation torque or variances in cavity/cartridge machining. Key specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, maximum operating pressure of 5000 psi (350 bar), and switching frequency up to 15000 cycles/hr. The compact and efficient design coupled with robust construction makes the DMDAXRV714 an excellent choice for demanding directional control applications in hydraulic systems.
