The Sun Hydraulics DMDAXRV624 (DMDAXRV624) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, making it highly effective in a variety of settings. It features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), ensuring durability and reliability under demanding conditions. The DMDAXRV624 valve is particularly noted for its closed transition spools (B and R), which do not allow flow between positions. This design enhances performance by providing faster and more consistent response times, ideal for use as pilot controls where capacity is less critical. The valve incorporates a wet armature design where the working fluid surrounds the armature; this setup requires consideration of fluid characteristics as heat generated by the coil during prolonged energization can degrade certain types of fluids. For manual override operations, this model includes a detent mechanism designed for temporary actuation with a mechanical life expectancy of around 7,000 cycles. It supports various manual control assemblies marked as D, L, or T types. With respect to compatibility with hydraulic fluids, cartridges equipped with EPDM seals are specifically intended for systems using phosphate ester fluids; exposure to petroleum-based fluids should be avoided to prevent seal damage. Additional features include interchangeable coils with other Sun Series 1 solenoid products and a floating style construction that minimizes internal parts binding due to installation torque or machining variations. The valve\u2019s specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response time of 50 ms. This makes the DMDAXRV624 suitable for high-frequency switching applications up to 15,000 cycles per hour, providing both robust performance and versatility in complex hydraulic systems.
