The Sun Hydraulics DMDAXNV548 (DMDAXNV548) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue rating for 5000 psi (350 bar) service, making it suitable for demanding applications. The valve operates with no minimum hydraulic pressure required, enhancing its versatility in various hydraulic circuits. Key specifications include a maximum flow capacity of 12 gpm (45 L/min) and a typical response time of 50 ms, ensuring quick and efficient operation. The valve is equipped with interchangeable coils from the Sun Series 1 solenoid products, which can be mounted in either direction to accommodate different installation requirements. Additionally, the DMDAXNV548 incorporates Sun's floating style construction to minimize internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. This model is particularly effective when used as pilot controls due to its closed transition between spool positions, which provides faster and more consistent response times despite a lower capacity. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended; however, these should not be exposed to petroleum-based fluids as they can damage the seals. The manual override feature is designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Overall, the Sun Hydraulics DMDAXNV548 offers robust performance and reliability for hydraulic systems requiring precise control and rapid response in industrial settings.

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.
