The Sun Hydraulics DMDAMAN924N (DMDAMAN924N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise control in hydraulic systems. This direct-acting, balanced spool directional valve is notable for its robust construction and the ability to operate without minimum hydraulic pressure, making it highly effective in a variety of applications. The valve features a fatigue rating for 5000 psi (350 bar) service, ensuring durability under high-pressure conditions. It includes spools B and R that are closed during the transition between positions, which enhances performance by providing faster and more consistent response times at the expense of lower flow capacity. This characteristic makes it particularly suitable for use as pilot controls where capacity is less critical. The manual override options (D, L, T control types) come with a detent mechanism designed for temporary actuation and boast a mechanical life expectancy of approximately 7,000 cycles. For environments using phosphate ester fluids, cartridges equipped with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as it can damage the seals. The valve's wet armature design means the working fluid surrounds the armature which can be heated by prolonged coil energization\u2014a consideration when using certain fluid types like water-glycol mixtures. This model also benefits from interchangeable coils with other Sun Series 1 solenoid products and incorporates Sun's floating style construction to minimize internal part binding caused by excessive installation torque or variations in cavity/cartridge machining. With a switching frequency capability of up to 15,000 cycles per hour and quick response times typically around 50 ms, the DMDAMAN924N is engineered for both reliability and high-speed operation in demanding applications.
