The Sun Hydraulics DMDAXBV814N (DMDAXBV814N) is a solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is specifically designed for high-performance applications with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). The valve features closed transitions between Spools B and R, optimizing performance by ensuring faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDAXBV814N operates without requiring a minimum hydraulic pressure, making it highly effective in various operational conditions. It includes options for manual override controls labeled as D, L, or T, which are intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The design incorporates EPDM seals suited for phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances to prevent damage. This model also benefits from a wet armature design where the working fluid surrounds the armature\u2014important to consider as prolonged energization can lead to fluid breakdown in certain conditions. The interchangeable coils compatible with other Sun Series 1 solenoid products add to its versatility and ease of use. Furthermore, the valve's construction minimizes internal parts binding due to installation torque or cavity/cartridge machining variations thanks to its floating style design. Key technical specifications include a typical response time of 50 ms, maximum leakage at 3000 psi rated at 5 in\u00b3/min., and switching frequency capable of reaching up to 15,000 cycles/hr. The manual override requires a force of about 5 lbs at 1000 psi for operation and has a stroke length of .10 inches. With its robust build and precise engineering, the Sun Hydraulics DMDAXBV814N valve is an essential component for systems requiring reliable directional control under high-pressure conditions.
