The Sun Hydraulics DMDAXPN214N (DMDAXPN214N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for use in advanced hydraulic systems. This direct-acting, balanced spool directional valve is essential for applications requiring precise control and reliability under high-pressure conditions up to 5000 psi (350 bar). The valve features a unique closed transition between spools B and R, which enhances performance by ensuring faster and more consistent response times, particularly suitable for pilot controls where capacity is less critical. The DMDAXPN214N operates without requiring a minimum hydraulic pressure, making it versatile for various operational scenarios. It includes manual override options with a detent mechanism designed for temporary actuation, supporting up to approximately 7,000 cycles. The valve's construction uses EPDM seals specifically intended for systems with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. Notably, the DMDAXPN214N incorporates a wet armature design where the working fluid surrounds the armature. This aspect is crucial as prolonged energization of the coil could elevate fluid temperatures affecting certain fluid types like water-glycol mixtures by causing breakdown and varnish formation that could impair cartridge function. Additionally, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This model also benefits from Sun's floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a flow capacity of 12 gpm (45 L/min) and rapid response times typically around 50 ms, this valve is optimized for both performance and durability in demanding hydraulic applications.
