The Sun Hydraulics DMDADPV814 (DMDADPV814) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve features a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure operations. It incorporates a closed transition between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The DMDADPV814 operates without requiring a minimum hydraulic pressure, which allows for its use in a variety of fluid power systems. The valve is equipped with an optional manual override (models with D or L control), which has a mechanical life expectancy of approximately 7,000 cycles. This feature is intended for temporary actuation only. For applications involving phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as it could damage the seals. This model uses a wet armature design where the working fluid surrounds the armature, potentially affecting fluid properties if the coil remains energized over extended periods. The interchangeable coils compatible with other Sun Series 1 solenoid products add to its versatility and ease of maintenance. Additionally, the valve's construction minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of up to 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at 110 SUS (24 cSt) being limited to 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The switching frequency can reach up to 15,000 cycles per hour, ensuring reliable operation under frequent use conditions.
