The Sun Hydraulics DMDATNN548 (DMDATNN548) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve that offers precise control in hydraulic systems. This direct-acting, balanced spool directional valve operates without the need for minimum hydraulic pressure, enhancing its reliability and ease of use across various applications. It features a fatigue-rated solenoid tube assembly designed to handle pressures up to 5000 psi (350 bar), making it suitable for rigorous industrial environments. The valve's construction includes spools B and R which are closed during the transition between positions to ensure higher performance limits, though this design choice results in reduced capacity. Such characteristics make it ideal for use as pilot controls where capacity is less critical but fast and consistent response times are necessary. The manual override included in models with D or L control is intended for temporary actuation, with a mechanical life expectancy of around 7,000 cycles. Equipped with EPDM seals, the DMDATNN548 cartridge is specifically configured for systems using phosphate ester fluids; however, these seals are susceptible to damage if exposed to petroleum-based fluids. Its wet armature design allows the working fluid to surround the armature which can be a consideration if the coil remains energized for extended periods due to potential breakdown of certain fluids like water-glycol mixtures. The valve also incorporates Sun's floating style construction which minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. With interchangeable coils compatible with other Sun Series 1 solenoid products and a maximum flow capacity of 12 gpm (45 L/min), this valve is versatile and robust enough for diverse operational requirements.

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.
