The Sun Hydraulics DMDAXPV828 (DMDAXPV828) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust and efficient control in hydraulic systems. This direct-acting, balanced spool directional valve ensures reliable operation without the need for minimum hydraulic pressure. It features a fatigue-rated solenoid tube assembly capable of handling up to 5000 psi (350 bar), making it suitable for demanding applications. The valve's construction includes spools B and R, which are closed during the transition between positions to enhance performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The DMDAXPV828 incorporates a wet armature design; the working fluid surrounds the armature which may affect fluid integrity under prolonged energization. Specific models with EPDM seals are designed for use with phosphate ester fluids, while exposure to petroleum-based fluids can damage these seals. This model also supports interchangeable coils with other Sun Series 1 solenoid products and offers flexibility in mounting direction on the tube. It features Sun's floating style construction that minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. The manual override mechanism provided in models equipped with D or L control is intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. With a maximum flow capacity of 12 gpm (45 L/min) and rapid response time typically around 50 ms, the DMDAXPV828 is well-suited for various hydraulic applications requiring precise control and reliability under high-pressure conditions. The valve also supports frequent switching, up to 15,000 cycles per hour, ensuring adaptability in complex system configurations.
