The Sun Hydraulics DMDAXRV (DMDAXRV) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for demanding hydraulic applications. It features a direct-acting, balanced spool with closed transitions between positions B and R, optimizing performance by ensuring faster and more consistent response times. This attribute makes the valve particularly suited for use as pilot controls where capacity is less critical but speed and reliability are paramount. The DMDAXRV operates without requiring a minimum hydraulic pressure, enhancing its versatility across various system conditions. It incorporates a wet armature design, meaning the working fluid not only activates the valve but also cools the solenoid coil. This design is critical in applications involving long energizing periods of the coil, although care must be taken with fluid selection to prevent breakdown and varnish formation that could impair operation. This model is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. For maintenance or temporary manual control, the valve includes a detent mechanism in models equipped with D or L control options, supporting up to approximately 7,000 cycles of mechanical life. Engineered for robust performance, the DMDAXRV can handle flow capacities up to 12 gpm (45 L/min) and withstand pressures up to 5000 psi (350 bar). Its construction utilizes Sun's floating style to minimize internal parts binding due to installation stresses or machining variations. Additionally, the coils of this valve series are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube, providing flexibility in system design and maintenance.
