The Sun Hydraulics DMDADNN298 (DMDADNN298) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and reliable operation under high pressures, being fatigue rated for 5000 psi (350 bar) service. It features a solenoid tube assembly that ensures durability and consistent performance. The DMDADNN298 model is equipped with closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for applications where capacity is less critical but speed and precision are necessary. Additionally, this valve does not require minimum hydraulic pressure to operate, which allows for flexibility in various hydraulic circuit configurations. For manual override operations, the DMDADNN298 includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The valve also supports different seal configurations; models with EPDM seals are specifically intended for use with phosphate ester fluids, avoiding damage from petroleum-based fluids. Its wet armature design helps in cooling but requires consideration of the fluid type used to prevent breakdowns from prolonged heat exposure. This model's interchangeability of coils with other Sun Series 1 solenoid products adds versatility in maintenance and replacement procedures. Furthermore, it incorporates Sun's floating style construction which minimizes internal parts binding\u2014a common issue due to installation torque or cavity/cartridge machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response time typically around 50 ms, the DMDADNN298 is an efficient solution for advanced hydraulic systems requiring precise control and reliability.
