The Sun Hydraulics DMDAXRN836 (Material Number DMDAXRN836) is a solenoid-operated 3-way, 2-position cartridge valve characterized by its direct-acting, balanced spool directional control. This valve is designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features a rapid response time of approximately 50 ms and is built with the capability to switch up to 15,000 cycles per hour, ensuring robust performance in demanding applications. The model incorporates a wet armature design which allows the working fluid to surround the armature, aiding in heat dissipation during prolonged energization periods. However, this design necessitates careful consideration of fluid type as heat can cause breakdowns in certain fluids like water-glycol mixtures. The valve's spools (B and R) are closed during the transition between positions, enhancing performance by providing faster and more consistent response times at the cost of reduced flow capacity. This valve is also equipped with manual override options (D or L control), featuring a detent mechanism designed for temporary actuation with an estimated mechanical life of around 7,000 cycles. The construction uses EPDM seals suitable for phosphate ester fluids but vulnerable to damage from petroleum-based fluids. Furthermore, it utilizes interchangeable coils from other Sun Series 1 solenoid products and can be mounted in either direction on the tube. The design includes Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This makes the DMDAXRN836 highly adaptable and reliable for various hydraulic control applications where precision and durability are crucial.
