The Sun Hydraulics DMDALPN72499 (DMDALPN72499) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool directional control. This model is particularly noted for its robust construction, including a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. The valve offers closed transitions between Spools B and R, enhancing performance limits at the cost of lower capacity, which is ideal for pilot control applications where capacity is less critical but fast and consistent response times are necessary. The DMDALPN72499 operates without requiring a minimum hydraulic pressure, making it highly effective in various operational contexts. It includes options for manual override through the D or L control detent mechanism, designed primarily for temporary actuation with a mechanical life expectancy of around 7,000 cycles. This model uses EPDM seals suitable for phosphate ester fluids but should not be exposed to petroleum-based fluids which could damage the seals. Furthermore, the valve incorporates a wet armature design allowing the working fluid to surround the armature and mitigate heat during prolonged coil energization \u2014 an important consideration when using certain fluids like water-glycol mixtures that may degrade under high temperatures. The interchangeable coils with other Sun Series 1 solenoid products add versatility to this model. It also benefits from Sun's floating style construction that minimizes internal parts binding due to installation variances or cavity/cartridge machining errors. This valve supports up to 12 gpm (45 L/min) capacity and features quick response times typically around 50 ms. Its design ensures minimal leakage and can handle switching frequencies up to 15,000 cycles/hr. Installation specifications include a solenoid tube diameter of .75 in (19 mm), hex size of 7/8 in (22.2 mm), and an installation torque between 30 - 35 lbf ft (41 -47 Nm). The compact and efficient design weighs only .60 lb (0.30 kg), making it suitable for various hydraulic applications requiring reliable directional control.
