The Sun Hydraulics DMDAMAN72499 (DMDAMAN72499) is a high-performance solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design suitable for various hydraulic applications. Engineered to operate at a maximum pressure of 5000 psi (350 bar) and with a flow capacity of up to 12 gpm (45 L/min), this valve ensures reliable control in hydraulic systems. Its quick response time, typically around 50 ms, and the ability to handle switching frequencies up to 15000 cycles per hour make it ideal for applications requiring frequent and precise operation. The DMDAMAN72499 incorporates advanced design features like closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times especially useful in pilot control setups where capacity is less critical. The wet armature design of the valve allows the working fluid to surround the armature, which helps in managing heat generated by the coil but requires careful consideration of fluid type to avoid breakdowns and varnish formation. This model also offers versatility in manual override options with its D, L, and T control types; however, these are intended for temporary actuation with a mechanical life expectancy of about 7,000 cycles. Additionally, it uses EPDM seals compatible with phosphate ester fluids but should avoid exposure to petroleum-based substances which could damage the seals. For ease of installation and maintenance, the valve features Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. Furthermore, its coils are interchangeable with other Sun Series 1 solenoid products providing additional flexibility in usage. The robust construction and thoughtful engineering make the DMDAMAN72499 an excellent choice for demanding hydraulic applications requiring high reliability and efficiency.
