The Sun Hydraulics DMDADNV828 (DMDADNV828) 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 solenoid tube assembly rated for fatigue at 5000 psi (350 bar), ensuring reliable operation under high-pressure conditions. The valve\u2019s spools, B and R, are closed in the transition between their two positions, enhancing performance by providing faster and more consistent response times, especially beneficial in pilot control applications where capacity is less critical. The DMDADNV828 requires no minimum hydraulic pressure to operate, making it versatile for various applications. It includes options for manual override controls (D, L, T) with a detent mechanism designed for temporary actuation and a mechanical life expectancy of approximately 7,000 cycles. The valve is equipped with EPDM seals suitable for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Featuring a wet armature design, the DMDADNV828 allows the working fluid to surround the armature which is beneficial but requires consideration of fluid type due to potential breakdown from prolonged heat exposure. Interchangeable coils with other Sun Series 1 solenoid products add to its adaptability and ease of use. Notably, its floating style construction minimizes internal parts binding from installation torque or machining variations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure capability of 5000 psi (350 bar). This model also supports switching frequencies up to 15,000 cycles per hour and incorporates manual override features that require minimal force. The compact design weighs only .60 lbs (0.30 kg), facilitating easy installation and maintenance.
