The Sun Hydraulics DMDAXAN848 (DMDAXAN848) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for rigorous hydraulic applications. This direct-acting, balanced spool directional valve is optimized for a maximum operating pressure of 5000 psi (350 bar) and features a fatigue-rated solenoid tube assembly. The valve's design ensures closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times particularly useful in pilot control applications where capacity is less critical. The DMDAXAN848 requires no minimum hydraulic pressure to operate, making it versatile across various hydraulic systems. It includes options for manual override with detent mechanisms (designated by D or L control) intended for temporary actuation, supporting a mechanical life expectancy of about 7,000 cycles. The wet armature design of the valve means that the working fluid surrounds the armature, which can be critical when considering fluid compatibility and coil operation durations. This model is compatible with EPDM seals specifically for use with phosphate ester fluids; however, these seals must avoid exposure to petroleum-based fluids to prevent damage. Additionally, the valve supports interchangeable coils with other Sun Series 1 solenoid products and incorporates Sun's floating style construction to minimize internal part binding due to installation variances. Key specifications include a flow capacity of up to 12 gpm (45 L/min), typical response time of 50 ms, maximum leakage at 3000 psi set at 5 in\u00b3/min., and a switching frequency capable of up to 15,000 cycles/hr. The manual override requires a force of about 5 lbs at 1000 psi on Port 1 with a stroke length of .10 inches. The model weighs approximately .60 lb (0.30 kg), ensuring it is lightweight yet robust for industrial applications.

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.
