The Sun Hydraulics DMDAXAN2E12V (DMDAXAN2E12V) is a solenoid-operated 3-way, 2-position cartridge valve that serves as a direct-acting, balanced spool directional valve. Engineered for high-performance applications, this valve features a solenoid tube assembly rated for fatigue at 5000 psi or 350 bar service. The DMDAXAN2E12V is particularly noted for its closed transition between Spools B and R, which ensures higher performance albeit with a reduced capacity. This model is designed to operate without any minimum hydraulic pressure, enhancing its versatility in various operating conditions. It includes options such as the D or L control with a manual override detent mechanism intended for temporary actuation, supporting approximately 7,000 mechanical life cycles. The valve is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. Additionally, the DMDAXAN2E12V utilizes a wet armature design where the working fluid surrounds the armature. This could lead to heat-related issues if the coil remains energized over extended periods since some fluids may degrade under high temperatures. For interchangeability and ease of maintenance, its coils can be swapped with other Sun Series 1 solenoid products and mounted in either direction on the tube. The construction incorporates Sun's floating style design which minimizes internal parts binding that might occur due to excessive installation torque or variations in cavity/cartridge machining. Specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). The valve also supports switching frequencies up to 15000 cycles per hour and has manual override features requiring minimal force. This precision-engineered valve is ideal for applications requiring reliable directional control in hydraulic systems.
