The Sun Hydraulics DMDALPN (DMDALPN) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This model is particularly noted for its robust construction which includes a fatigue-rated solenoid tube assembly suitable for up to 5000 psi or 350 bar service. The valve features closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, ideal for applications requiring precise control such as in pilot operations where capacity is less critical. Engineered with a wet armature design, the DMDALPN allows the working fluid to surround the armature which helps in managing the heat generated by the coil. However, this design consideration means that it's crucial to select appropriate fluids; for instance, water-glycol mixtures might degrade under prolonged exposure to high temperatures. It\u2019s also equipped with EPDM seals suitable for systems using phosphate ester fluids but incompatible with petroleum-based fluids which could damage these seals. With a maximum operating capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, this valve ensures efficient flow control in your hydraulic systems. It supports a maximum switching frequency of 15000 cycles/hr and can handle maximum valve leakage at 110 SUS (24 cSt) up to 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). For maintenance or manual operation, it includes a manual override feature requiring minimal force. The DMDALPN also benefits from Sun Hydraulics' floating style construction which minimizes internal parts binding\u2014this feature is critical in installations where there might be variations in cavity or cartridge machining. This model is compatible with other Sun Series 1 solenoid products concerning coil interchangeability and can be mounted on the tube in either direction to suit various installation requirements.
