The Sun Hydraulics DMDAXBN924N (DMDAXBN924N) 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 operates without the need for minimum hydraulic pressure, enhancing its reliability and performance across various applications. It features a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for rigorous industrial use. The valve's construction includes B and R spools that are closed during the transition between positions, which minimizes leakage and ensures a more consistent response time\u2014ideal for pilot control applications where rapid actuation is crucial. The manual override option, available with D or L control types, incorporates a detent mechanism designed primarily for temporary actuation with a mechanical life expectancy of about 7,000 cycles. For environments using phosphate ester fluids, cartridges equipped with EPDM seals are recommended to prevent damage from petroleum-based substances. Additionally, the wet armature design of the valve helps in cooling but requires consideration regarding the type of fluid used due to potential breakdowns from prolonged heat exposure. Interchangeability is another significant feature; the coils are compatible with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. This flexibility is complemented by Sun's floating style construction that minimizes internal part binding caused by installation torque or machining variations. With a maximum flow capacity of 12 gpm (45 L/min) and swift response times typically around 50 ms, the DMDAXBN924N is adept at managing fluid power efficiently in various configurations while maintaining robust performance and durability. This makes it an essential component for systems requiring precise directional control of hydraulic fluids under high-pressure conditions.

This solenoid-operated 3-way, 2-position cartridge is a direct-acting, balanced spool directional valve.
- The solenoid tube assembly is fatigue rated for 5000 psi (350 bar) service.
- Spools B and R are closed in the transition between their two positions. This results in a higher performance limit at the expense of lower capacity. When used as pilot controls, where capacity is not a factor, the closed transition will provide faster and more consistent response times.
- This valve is direct actuated and requires no minimum hydraulic pressure for operation.
- On models equipped with the D or L control, the detent mechanism in the manual override is meant for temporary actuation. The D, L and T manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- Cartridges configured with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- This valve utilizes a wet armature design. This means that the working fluid surrounds the armature and is exposed to the heat generated by the coil. This can be a factor if the coil is energized for long periods of time. Some fluids, notably water/glycol mixtures, break down at these temperatures over time and form varnishes that will affect the function of the cartridge.
- Coils are interchangeable with other Sun Series 1 solenoid products and can be mounted on the tube in either direction.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
