The Sun Hydraulics DMDALPN223 (DMDALPN223) is a solenoid-operated 3-way, 2-position cartridge valve that serves as a direct-acting, balanced spool directional control valve. This model is designed to operate without minimum hydraulic pressure and features a balanced spool with closed transitions between positions B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for applications as pilot controls. The DMDALPN223 is fatigue rated for 5000 psi (350 bar), making it robust for high-pressure applications. The valve includes a manual override with a detent mechanism intended for temporary actuation, boasting a mechanical life expectancy of about 7,000 cycles. It employs EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature, which could lead to breakdowns in certain fluid types if the coil remains energized over extended periods. This model also features interchangeable coils compatible with other Sun Series 1 solenoid products and incorporates Sun\u2019s floating style construction which minimizes internal parts binding. It supports up to 12 gpm (45 L/min) capacity and can handle maximum operating pressures up to 5000 psi (350 bar). The DMDALPN223 has quick response times typically around 50 ms and maintains operational integrity with maximum valve leakage well controlled at high pressures. Additionally, it supports high switching frequencies up to 15,000 cycles/hr making it an efficient choice for repetitive tasks requiring precise control.
