The Sun Hydraulics DMDAXAN948 (DMDAXAN948) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for rigorous hydraulic applications. This direct-acting, balanced spool directional valve operates with no minimum hydraulic pressure required, making it highly versatile in a range of operational contexts. It features a fatigue-rated solenoid tube assembly suitable for up to 5000 psi (350 bar) service, ensuring durability and reliability under high-pressure conditions. The DMDAXAN948 valve is equipped with closed transitions between spool positions B and R, enhancing performance by providing faster and more consistent response times ideal for pilot control applications where capacity is less critical. The manual override feature included in models with D or L control is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Additionally, the valve incorporates EPDM seals configured specifically for use with phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. This model also employs a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged coil energization can lead to fluid breakdown at high temperatures, potentially affecting cartridge function. For maintenance and compatibility ease, the coils of this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction on the tube. Sun Hydraulics has integrated its floating style construction into the DMDAXAN948 to minimize internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. This feature ensures smoother operation and increased operational longevity of the valve in dynamic hydraulic systems.

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.
