The Sun Hydraulics DMDAXBN224 (DMDAXBN224) is a solenoid-operated 3-way, 2-position cartridge valve that excels in direct-acting, balanced spool directional control. Designed for robust performance, this valve features a fatigue rating of 5000 psi (350 bar), making it suitable for high-pressure applications. It operates with no minimum hydraulic pressure requirement, ensuring reliable functionality under diverse operating conditions. The DMDAXBN224 is engineered with closed transition spools (B and R), which do not allow flow between positions; this design enhances the valve's performance by providing faster and more consistent response times, particularly beneficial when used as pilot controls in systems where flow capacity is less critical. Additionally, the valve incorporates manual override options with a detent mechanism designed for temporary actuation, supporting a mechanical life expectancy of approximately 7,000 cycles. For compatibility with different fluid types, cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; however, these should not be exposed to petroleum-based fluids as it could damage the seals. The valve\u2019s wet armature design allows the working fluid to surround the armature which can be a consideration if the coil remains energized over extended periods due to potential breakdown of certain fluids like water-glycol mixtures. Interchangeability of coils with other Sun Series 1 solenoid products adds versatility to this model, allowing coils to be mounted in either direction on the tube. The construction includes Sun\u2019s floating style design which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With features such as a maximum operating pressure of 5000 psi (350 bar), a flow capacity up to 12 gpm (45 L/min), and rapid response times typically around 50 ms, the DMDAXBN224 is an effective solution for directing flow in hydraulic systems requiring precise control and high reliability.
