The Sun Hydraulics DMDAMPV298 (DMDAMPV298) is a solenoid-operated 3-way, 2-position cartridge valve that exemplifies precision and reliability in hydraulic control systems. This direct-acting, balanced spool directional valve is designed to operate seamlessly without the need for minimum hydraulic pressure, making it highly efficient in a variety of applications. The valve features spools B and R which are closed during the transition between positions, enhancing performance by ensuring faster and more consistent response times particularly suitable for pilot controls where capacity is less critical. With a robust solenoid tube assembly rated for fatigue at 5000 psi (350 bar), the DMDAMPV298 ensures durability even under high-pressure conditions. This model incorporates EPDM seals ideal for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. The wet armature design of the valve helps in cooling but requires consideration of fluid characteristics as prolonged exposure to heat can degrade certain types of hydraulic fluids. This versatile cartridge valve supports interchangeable coils with other Sun Series 1 solenoid products and offers flexibility in mounting direction on the tube. It also benefits from Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or machining variations of cavity/cartridge. The manual override feature includes a detent mechanism designed for temporary actuation with an expected mechanical life of approximately 7,000 cycles. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and rapid response times typically around 50 ms. The DMDAMPV298 is also designed for easy integration with a T11A cavity type and adheres to stringent leakage standards ensuring operational efficiency and reliability in demanding environments.
