The Sun Hydraulics DMDADBV828 (DMDADBV828) is a solenoid-operated 3-way, 2-position cartridge valve that stands out for its direct-acting, balanced spool directional capabilities. Designed for robustness and precision, the valve operates with no minimum hydraulic pressure requirement, making it versatile across various applications. It features a fatigue rating for 5000 psi (350 bar) service, ensuring durability under high-pressure conditions. This model incorporates Sun Hydraulics' innovative floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The DMDADBV828 is engineered with spools B and R that are closed during transitions between positions, enhancing performance limits at the cost of lower capacity\u2014ideal for pilot controls where capacity is less critical but response time and consistency are paramount. The valve's manual override mechanism is designed for temporary actuation only, with a mechanical life expectancy of approximately 7,000 cycles. It utilizes EPDM seals suitable for systems using phosphate ester fluids; however, these seals are sensitive to petroleum-based fluids which can cause damage. Additionally, the wet armature design allows the working fluid to surround the armature and be exposed to heat generated by the coil\u2014a factor to consider if the coil remains energized over extended periods. Interchangeability of coils with other Sun Series 1 solenoid products adds to its flexibility in use, allowing mounting on the tube in either direction. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times around 50 ms. This model also supports switching frequencies up to 15,000 cycles/hr and features manual override requirements tailored for ease of use under varying pressures.
