The Sun Hydraulics DMDALNN248 (DMDALNN248) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed for robust and efficient performance with a maximum operating pressure of 5000 psi (350 bar) and a capacity of 12 gpm (45 L/min). The DMDALNN248 features a fatigue-rated solenoid tube assembly suitable for demanding applications, ensuring reliability under continuous use. Key to its design is the closed transition between positions in Spools B and R, which optimizes performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls. This valve requires no minimum hydraulic pressure to operate, making it versatile across various hydraulic systems. The manual override option in models with the D or L control includes a detent mechanism designed for temporary actuation, supporting approximately 7,000 cycles mechanically. The wet armature design of the DMDALNN248 ensures that the working fluid surrounds the armature which can be critical when considering the thermal effects during prolonged energization. It's important to note that cartridges with EPDM seals are intended for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. Additionally, this model incorporates Sun\u2019s floating style construction which minimizes internal parts binding \u2014 a common issue arising from excessive installation torque or cavity/cartridge machining variations. Interchangeability of coils with other Sun Series 1 solenoid products adds to the flexibility and ease of use of this valve, allowing mounting on the tube in either direction to suit different system configurations. With its robust construction and adaptable features, the Sun Hydraulics DMDALNN248 is ideal for applications requiring precise control and reliability in high-pressure environments.
