The Sun Hydraulics DMDAXNV299 (DMDAXNV299) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. Designed for direct-acting operation, this balanced spool directional valve does not require a minimum hydraulic pressure to function. It features a fatigue-rated solenoid tube assembly for up to 5000 psi (350 bar) service, ensuring durability and reliability in demanding applications. The valve's spools, B and R, are closed during the transition between positions which enhances performance limits at the cost of lower capacity. However, this configuration is ideal in pilot control applications where capacity is less critical but fast and consistent response times are crucial. The DMDAXNV299 incorporates manual override options with detent mechanisms intended for temporary actuation; these controls are designed to withstand approximately 7,000 cycles. For environments using phosphate ester fluids, cartridges equipped with EPDM seals are recommended to avoid damage from petroleum-based substances. The wet armature design of the valve allows the working fluid to surround the armature which can be susceptible to heat during prolonged coil energization; this should be considered when using certain fluids like water-glycol mixtures. This model is compatible with other Sun Series 1 solenoid products as its coils are interchangeable and can be mounted in either direction on the tube. It also benefits from Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. With a typical response time of 50 ms and capable of handling up to 12 gpm (45 L/min), this valve is a robust choice for various hydraulic applications requiring precise control and reliable operation under high pressure conditions.
