The Sun Hydraulics DMDADNN924N (DMDADNN924N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is notable for its robust construction, featuring a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. The valve's spools (B and R) remain closed during the transition between positions, enhancing performance by ensuring faster and more consistent response times, particularly suitable for applications where capacity is less critical. The DMDADNN924N operates without requiring a minimum hydraulic pressure, making it highly effective in various operational scenarios. It includes options for manual override through D, L, or T control mechanisms; however, these are intended primarily for temporary actuation with a mechanical life expectancy of around 7,000 cycles. For environments utilizing phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based substances. This model also employs a wet armature design which helps in heat management but requires consideration regarding the type of fluid used due to potential breakdowns under prolonged heat exposure. The interchangeable coils compatible with other Sun Series 1 solenoid products add versatility to its application across different setups. Additionally, the innovative Sun floating style construction minimizes internal parts binding caused by installation stresses or machining variations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), an impressive switching frequency of up to 15,000 cycles per hour, and quick response times typical at around 50 ms. Installation features like a hex size of 7/8 inch (22.2 mm) and torque requirements between 30 - 35 lbf.ft (41 - 47 Nm), along with minimal leakage rates at high pressures ensure reliable and efficient operation in demanding hydraulic systems.
