The Sun Hydraulics DMDAMRN636 (DMDAMRN636) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for demanding hydraulic applications. This direct-acting, balanced spool directional valve operates without requiring a minimum hydraulic pressure, making it extremely versatile for various operational contexts. The unit features a fatigue rating of 5000 psi (350 bar), ensuring durability and robust performance under high-pressure conditions. The valve's construction includes a solenoid tube assembly that is interchangeable with other Sun Series 1 solenoid products, allowing for flexible use and replacement. It can be mounted in either direction on the tube to accommodate different installation requirements. The design incorporates Sun's floating style construction which minimizes internal parts binding and potential damage due to excessive installation torque or cavity/cartridge machining variations. This model is equipped with EPDM seals suitable for systems using phosphate ester fluids, while exposure to petroleum-based fluids should be avoided to prevent seal damage. The wet armature design of the valve means that the working fluid surrounds the armature; this could be a consideration if the coil remains energized for extended periods as some fluids may degrade under prolonged exposure to heat. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times around 50 ms. It also supports manual override functions with specific force requirements and stroke limits, enhancing operational flexibility. This model weighs approximately 0.60 lb (0.30 kg) and requires an installation torque between 30 - 35 lbf ft (41 - 47 Nm). With its robust build and adaptable features, the DMDAMRN636 is engineered for efficient performance in complex hydraulic systems.
