The Sun Hydraulics DMDALPN212 (DMDALPN212) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and efficient control in hydraulic systems. Featuring a fatigue rating of 5000 psi (350 bar), the DMDALPN212 is built to handle demanding applications. The valve operates with no minimum hydraulic pressure required, ensuring reliable performance across a wide range of conditions. The DMDALPN212 incorporates closed transitions between Spools B and R, which enhances performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. It also features a wet armature design where the working fluid surrounds the armature; this can be relevant when considering fluid type as some fluids may degrade at higher temperatures. For manual operation, models equipped with the D or L control have a detent mechanism designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The valve\u2019s manual override requires minimal force, enhancing usability in field adjustments. This model uses EPDM seals suitable for systems utilizing phosphate ester fluids; however, these seals are not compatible with petroleum-based fluids which can cause damage. Additionally, the interchangeable coils compatible with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement procedures. With features like the Sun floating style construction to minimize internal parts binding and an installation torque of 30 - 35 lbf ft (41 - 47 Nm), the DMDALPN212 ensures a reliable and efficient operation in various hydraulic applications while preventing common issues related to excessive torque or machining variations in cartridge installation.
