The Sun Hydraulics DMDAMPV224N (DMDAMPV224N) is a solenoid-operated 3-way, 2-position cartridge valve that stands out due to its direct-acting, balanced spool design. This valve is specifically engineered for high-performance applications with a fatigue rating suitable for 5000 psi (350 bar) service. The DMDAMPV224N features closed transitions between spool positions B and R, enhancing performance by ensuring faster and more consistent response times, particularly beneficial in pilot control applications where capacity is less critical. The valve operates without requiring a minimum hydraulic pressure, making it versatile for various system conditions. It includes a manual override with a detent mechanism designed for temporary actuation, supporting mechanical life expectancy around 7,000 cycles. This model is compatible with EPDM seals intended for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. A notable feature of the DMDAMPV224N is its wet armature design; the working fluid envelops the armature which may be subject to heat during prolonged coil energization. This aspect necessitates consideration of fluid type as some may degrade under heat, affecting cartridge functionality. The valve's design allows interchangeable coils with other Sun Series 1 solenoid products and offers flexibility in mounting direction on the tube. Incorporating Sun's floating style construction minimizes internal part binding risks due to excessive installation torque or variations in cavity/cartridge machining. The valve supports up to 12 gpm (45 L/min) capacity and can handle switching frequencies up to 15,000 cycles/hr. Its quick response time (typically 50 ms), minimal leakage at high pressures (5 in\u00b3/min at 3000 psi), and robust manual override features make it an efficient choice for demanding directional control applications in hydraulic systems.
