The Sun Hydraulics DMDAXRV236 (DMDAXRV236) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust and efficient control in hydraulic systems. It features a fatigue-rated solenoid tube assembly capable of handling service pressures up to 5000 psi (350 bar). The valve\u2019s design includes closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. This model operates without requiring a minimum hydraulic pressure, making it versatile for various applications. The DMDAXRV236 is equipped with manual override options (D or L control), designed primarily for temporary actuation with a mechanical life expectancy of around 7,000 cycles. It also incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. The wet armature design of the valve ensures the working fluid surrounds the armature which may be significant when the coil is energized continuously as it could lead to breakdown or varnish formation in certain fluids like water-glycol mixtures. Additionally, its coils are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Noteworthy specifications include a maximum flow capacity of 12 gpm (45 L/min), a typical response time of 50 ms, and an operational switching frequency up to 15000 cycles per hour. The manual override requires a force of about 5 lbs at 1000 psi at Port 1 and has a stroke length of .10 inches (2.5 mm). Installation employs Sun\u2019s floating style construction which minimizes internal parts binding due to excessive torque or machining variations during cavity-cartridge installation.
