The Sun Hydraulics DMDATPN214N (DMDATPN214N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for direct-acting and balanced spool directional control. This model features a solenoid tube assembly that is fatigue rated for 5000 psi (350 bar) service, ensuring robust operation under high-pressure conditions. The valve's spools B and R remain closed during transitions between positions to enhance performance limits at the expense of lower capacity. This characteristic makes it particularly suitable for pilot controls where capacity is less critical but fast and consistent response times are essential. The DMDATPN214N operates without requiring a minimum hydraulic pressure, which enhances its versatility in various applications. It includes optional manual overrides with a detent mechanism (designated by D or L control), primarily intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. The valve is also compatible with EPDM seals when used in systems containing phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. Additionally, the wet armature design of the valve allows the working fluid to surround the armature, which can be beneficial or detrimental depending on the duration the coil is energized and the type of fluid used. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. The construction incorporates Sun\u2019s floating style to minimize internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at 110 SUS (24 cSt) being only 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). These features make the DMDATPN214N an efficient solution for demanding directional control applications where reliability and precision are critical.
