The Sun Hydraulics DMDAMNV624N (DMDAMNV624N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. It features a direct-acting, balanced spool design which ensures reliable operation without the need for minimum hydraulic pressure. This valve is particularly noted for its robust construction, including a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. The spools in the B and R configurations are closed during transition, enhancing performance by ensuring faster and more consistent response times at the cost of lower capacity, which is not a concern in pilot control applications. This model incorporates advanced features such as interchangeable coils with other Sun Series 1 solenoid products, allowing flexible installation orientations. It also employs a wet armature design where the working fluid surrounds the armature, thus requiring consideration of fluid type due to potential heat exposure effects on fluid integrity over extended periods. The DMDAMNV624N uses EPDM seals optimized for phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based substances. The valve is designed with manual override options that are intended for temporary actuation only; these include controls labeled D, L, and T with a mechanical life expectancy around 7,000 cycles. Other technical specifications include a flow capacity of 12 gpm (45 L/min), rapid response time typically around 50 ms, and maximum operating pressure capabilities up to 5000 psi (350 bar). Additionally, it features Sun\u2019s floating style construction which minimizes internal parts binding caused by installation torque or machining variations in cavity/cartridge. This makes the DMDAMNV624N an excellent choice for applications requiring precise control with high reliability and durability.
