The Sun Hydraulics DMDAXPV298 (DMDAXPV298) is a solenoid-operated 3-way, 2-position cartridge valve that offers precise control in hydraulic systems. This direct-acting, balanced spool directional valve is designed for high-performance applications with its fatigue rating of 5000 psi (350 bar). The valve features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, particularly suitable for pilot control applications where capacity is less critical. The DMDAXPV298 operates without requiring a minimum hydraulic pressure, enhancing its versatility in various system configurations. It includes options for manual override controls (D or L control), which are primarily intended for temporary actuation with a mechanical life expectancy of around 7,000 cycles. The valve\u2019s wet armature design means the working fluid surrounds the armature, which is crucial to consider as prolonged energization can lead to fluid breakdown in certain conditions. This model is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. For ease of integration and maintenance, the coils of the DMDAXPV298 are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Additionally, this valve incorporates Sun's floating style construction which minimizes internal parts binding that could result from excessive installation torque or variations in cavity/cartridge machining. With a maximum operating capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, the DMDAXPV298 proves to be an efficient solution for dynamic system requirements while maintaining robustness and reliability in demanding environments.
