The Sun Hydraulics DMDAMBV814 (DMDAMBV814) is a solenoid-operated 3-way, 2-position cartridge valve that functions as a direct-acting, balanced spool directional valve. This model is specifically designed to deliver robust performance with its fatigue-rated solenoid tube assembly for 5000 psi (350 bar) service. The valve features closed transitions between Spools B and R, optimizing performance by enabling faster and more consistent response times, particularly beneficial when used as pilot controls where capacity is less critical. The DMDAMBV814 operates without requiring a minimum hydraulic pressure, enhancing its versatility in various applications. It includes options for manual override through the D or L control, with a mechanical life expectancy of about 7,000 cycles for these components. Notably, this model uses EPDM seals suitable for systems utilizing phosphate ester fluids; however, these seals are vulnerable to damage when exposed to petroleum-based substances. Further enhancing its utility, the valve's wet armature design allows the working fluid to surround the armature which helps manage the heat generated by the coil\u2014important when the coil remains energized over extended periods. Interchangeability of coils with other Sun Series 1 solenoid products adds to its flexibility in use, and its floating style construction minimizes risks of internal parts binding due to variations in installation torque or cavity/cartridge machining. The valve supports a maximum flow capacity of 12 gpm (45 L/min) and can handle up to 5000 psi (350 bar) pressure. It offers rapid response times typically around 50 ms and maintains a switching frequency up to 15,000 cycles/hr. Installation specifications include a manual override force requirement of approximately 5 lbs at 1000 psi for Port 1 and an installation torque range between 30-35 lbf-ft (41-47 Nm). The compact model weighs about .60 lb (0.30 kg), making it suitable for various industrial applications requiring precise fluid control.
