The Sun Hydraulics DNDAMYV223 (DNDAMYV223) is a solenoid-operated, 4-way, 2-position cartridge valve designed for direct-acting, balanced spool directional control. This valve is engineered for robust performance with a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar). Notably, it requires no minimum hydraulic pressure for operation, making it versatile in various applications. The valve features several manual override options, although these are incompatible with weatherized coils. It includes models with D or L control that have a detent mechanism intended for temporary actuation and offers approximately 7,000 cycles of mechanical life expectancy. The cartridge is compatible with EPDM seals, specifically suited for systems using phosphate ester fluids but not recommended for petroleum-based fluids due to potential seal damage. Utilizing a wet armature design, the valve ensures that the working fluid surrounds the armature and manages heat generated by the coil\u2014important when coils are energized over extended periods as some fluids may degrade under these conditions. Offering a wide range of coil termination and voltage options\u2014with or without surge protection\u2014the valve's magnetic design enhances efficiency by providing high spool actuating force per watt expended. This leads to reliable valve shifting performance. It also features interchangeable coils compatible with other Sun Series 1 solenoid products and accommodates mounting in either direction. Coil connector options achieve ratings up to IP69K for enhanced environmental protection. The DNDAMYV223 incorporates Sun's floating style construction to minimize internal part binding from excessive installation torque or cavity/cartridge machining variations. It fits into cavity T-31A and belongs to Series 1, offering a capacity of 10 gpm (40 L/min) and a typical response time of 50 ms. The valve supports a maximum leakage rate of 10 in\u00b3/min at 3000 psi (160 cc/min at 210 bar), switching frequency up to 15,000 cycles/hr, and has specific manual override force requirements and stroke dimensions tailored for optimal performance in hydraulic systems.
