The Sun Hydraulics DMDAMAV824 (DMDAMAV824) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to operate seamlessly without the need for minimum hydraulic pressure. It features a fatigue-rated solenoid tube assembly capable of handling services up to 5000 psi (350 bar), making it robust for demanding applications. The valve's spools, B and R, are closed during the transition between positions, which enhances performance by enabling faster and more consistent response times ideal for pilot control applications where capacity is less critical. This model incorporates a wet armature design, where the working fluid surrounds the armature; this is crucial in applications where the coil may be energized for extended periods as it can affect fluid integrity over time. The valve also boasts interchangeable coils with other Sun Series 1 solenoid products and supports a mounting capability in either direction on the tube. Additional features include a manual override with a detent mechanism designed for temporary actuation and an expected mechanical life of approximately 7,000 cycles. The manual override requires minimal force and has a short stroke distance for user convenience. With its floating style construction, the DMDAMAV824 minimizes internal parts binding caused by excessive installation torque or machining variations in cavity/cartridge. The valve offers impressive technical specifications such as a maximum flow capacity of 12 gpm (45 L/min), typical response times of around 50 ms, and maximum leakage at high pressures kept to minimal levels. It supports frequent switching up to 15,000 cycles per hour and can handle manual override forces efficiently even under high pressure settings. This model is specifically configured with EPDM seals suitable for systems using phosphate ester fluids but should avoid exposure to petroleum-based substances to maintain seal integrity.
