The Sun Hydraulics DMDAXNN836 (DMDAXNN836) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service. Its design ensures closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times particularly in pilot control applications where capacity is less critical. With no minimum hydraulic pressure required for operation, the DMDAXNN836 offers flexibility across various applications. It incorporates manual override options with D, L, and T controls; however, these are intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The valve is equipped with EPDM seals configured specifically for use with phosphate ester fluids; exposure to petroleum-based fluids can damage these seals. The wet armature design of the valve allows the working fluid to surround the armature, which can heat up during prolonged energization \u2014 an important consideration when using certain fluid types like water-glycol mixtures that may degrade under high temperatures. Interchangeable coils compatible with other Sun Series 1 solenoid products add to the versatility of this model. Additionally, the DMDAXNN836 utilizes Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. This construction feature along with a robust build ensures reliable operation and extends the product's operational lifespan under demanding conditions. The valve supports up to 12 gpm (45 L/min) capacity and includes features like a maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and manual override capabilities that require minimal force.
