The Sun Hydraulics DMDAMAV514 (DMDAMAV514) 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 for up to 5000 psi (350 bar) service, ensuring durability and reliability in demanding applications. The valve's spools, B and R, are closed during the transition between positions to enhance performance limits at the expense of lower capacity. However, this characteristic makes it ideal for pilot controls where capacity is less critical but faster and more consistent response times are beneficial. The DMDAMAV514 operates without requiring a minimum hydraulic pressure, adding to its versatility across various hydraulic applications. It includes optional manual control assemblies (D, L, T) with a mechanical life expectancy of about 7,000 cycles and features temporary actuation through its detent mechanism in the manual override. Special configurations with EPDM seals are available for compatibility with phosphate ester fluids; however, these should not be exposed to petroleum-based substances which can degrade the seals. This model also benefits from a wet armature design allowing the working fluid to cool the armature directly\u2014useful in preventing overheating during prolonged energization of the coil. Users should note that some fluids may degrade under extended high temperatures. Interchangeability with other Sun Series 1 solenoid products provides additional flexibility and ease of use by allowing coils to be mounted in either direction on the tube. With a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and quick response times typically around 50 ms, the DMDAMAV514 is an effective solution for advanced hydraulic system designs requiring precise control and reliability.
