The Sun Hydraulics DMDAMPV712 (DMDAMPV712) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. The valve features a direct-acting, balanced spool with closed transitions between positions B and R, enhancing performance at the cost of capacity. This design choice is particularly beneficial in applications where rapid and consistent response times are critical, such as pilot controls where capacity is less crucial. Constructed to be fatigue-rated for 5000 psi (350 bar) service, the DMDAMPV712 ensures durability and reliability in demanding environments. It operates without requiring a minimum hydraulic pressure, which allows for flexibility in various hydraulic systems. The valve incorporates a wet armature design where the working fluid surrounds the armature; this could influence fluid integrity if exposed to prolonged heat from an energized coil. The manual override feature on models equipped with D or L control is intended for temporary actuation only, with a mechanical life expectancy of approximately 7,000 cycles. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended to prevent damage from petroleum-based substances. Further enhancing its adaptability, the solenoid coils of the DMDAMPV712 are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The valve also benefits from Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or variations in cavity/cartridge machining. 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). The valve is designed to minimize leakage and supports switching frequencies up to 15,000 cycles per hour. This makes the DMDAMPV712 an excellent choice for applications requiring robust performance and high reliability in directional control operations.
