The Sun Hydraulics DMDAMPN223 (DMDAMPN223) 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 engineered to operate efficiently with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). It features closed transitions between spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly suitable for applications where capacity is less critical. The DMDAMPN223 incorporates a wet armature design allowing the working fluid to surround the armature, which can be crucial in scenarios where the coil is energized for extended periods. This model is compatible with EPDM seals specifically for use with phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. Its manual override mechanism is designed for temporary actuation, with a mechanical life expectancy of approximately 7,000 cycles. For installation flexibility, the coils of this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The unit also utilizes Sun\u2019s floating style construction to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. This model's robust design includes features like a typical response time of 50 ms and maximum leakage at 110 SUS (24 cSt) being limited to 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). It supports switching frequencies up to 15,000 cycles/hr, making it an ideal choice for rigorous industrial applications requiring reliable and precise control. The manual override requires a force of about 5 lbs at 1000 psi on Port 1 (33 N at 100 bar on Port 1), ensuring easy operation under varying pressure conditions.
