The Sun Hydraulics DMDAXNN548 (DMDAXNN548) is a solenoid-operated 3-way, 2-position cartridge valve that offers precise control in hydraulic systems. This direct-acting, balanced spool directional valve is designed to operate without minimum hydraulic pressure and features a fatigue rating for 5000 psi (350 bar) service, making it suitable for high-pressure applications. The spools B and R maintain a closed position during the transition between two positions, which enhances performance limits at the cost of lower capacity. However, in pilot control applications where capacity is less critical, this feature allows for faster and more consistent response times. The valve incorporates an innovative wet armature design wherein the working fluid surrounds the armature. This setup needs careful consideration as prolonged energization can lead to fluid degradation due to heat exposure. The valve's manual override is equipped with a detent mechanism intended for temporary actuation only, with a mechanical life expectancy of about 7,000 cycles. For compatibility with different system fluids, cartridges configured with EPDM seals are specifically designed for use with phosphate ester fluids; these seals are susceptible to damage when exposed to petroleum-based fluids. Additionally, the interchangeable coils of this model can be mounted on the tube in either direction and are compatible with other Sun Series 1 solenoid products. The DMDAXNN548 also features Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. With a typical response time of 50 ms and capable of handling up to 12 gpm (45 L/min), this model ensures reliable operation and switching frequency up to 15,000 cycles/hr. The design details such as manual override force requirement and stroke, solenoid tube diameter, hex size, installation torque specifications further affirm its utility and ease of integration into various 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.
