The Sun Hydraulics DMDAXBN548 (DMDAXBN548) 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 features a robust design with a fatigue rating of 5000 psi (350 bar), making it suitable for demanding applications. The valve's solenoid tube assembly ensures reliable operation under high-pressure conditions. Equipped with EPDM seals, the DMDAXBN548 is specifically configured for use with phosphate ester fluids; however, it is important to avoid exposure to petroleum-based fluids which can damage the seals. The valve incorporates a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization of the coil could lead to fluid degradation if not properly managed. The DMDAXBN548 offers interchangeable coils with other Sun Series 1 solenoid products and can be mounted in either direction on the tube for flexible installation options. It also features Sun\u2019s floating style construction which minimizes internal part binding due to installation torque or machining variations of cavity/cartridge. With a capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, this valve ensures efficient operation and control. It supports a maximum operating pressure up to 5000 psi (350 bar) and has a manual override feature with a detent mechanism designed for temporary actuation only. The mechanical life expectancy of this manual control assembly is about 7,000 cycles, underlining its durability for repetitive use scenarios. Overall, the Sun Hydraulics DMDAXBN548 valve is an essential component for systems requiring reliable and precise flow direction control under high-pressure conditions while ensuring compatibility with specific hydraulic fluids.

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.
