The Sun Hydraulics DMDAMNV (DMDAMNV) is a solenoid-operated 3-way, 2-position cartridge valve, specifically designed as a direct-acting, balanced spool directional valve. It features a solenoid tube assembly that is fatigue rated for high-pressure service up to 5000 psi (350 bar). The valve's design includes closed transitions between spool positions B and R, enhancing performance limits while sacrificing some capacity. This characteristic makes the valve particularly effective when used as pilot controls where capacity is less critical. The DMDAMNV operates without requiring a minimum hydraulic pressure, making it versatile for various applications. Certain models of this valve come with manual override options (D, L, or T control), which include a detent mechanism intended for temporary actuation; these manual controls are designed to withstand approximately 7,000 cycles. The valve also features cartridges with EPDM seals suitable for systems using phosphate ester fluids; however, these seals are susceptible to damage by petroleum-based products. This model utilizes a wet armature design where the working fluid surrounds the armature. This setup needs consideration in applications where the coil may be energized continuously, as some fluids can degrade under prolonged exposure to heat. The interchangeable coils with other Sun Series 1 solenoid products add flexibility in maintenance and replacement processes. Moreover, Sun Hydraulics has incorporated their floating style construction into this model to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With specifications like a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times around 50 ms, the DMDAMNV offers robust performance for demanding applications.
