The Sun Hydraulics DMDAXNN928 (DMDAXNN928) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve operates without the need for a minimum hydraulic pressure, enhancing its responsiveness and reliability in various applications. It features a fatigue rating of 5000 psi (350 bar), making it suitable for rigorous industrial use. The valve's solenoid tube assembly is specifically engineered to handle high-pressure applications with enhanced durability. The spools in the B and R configurations are closed during transition, which, while limiting capacity, significantly boosts performance by ensuring faster and more consistent response times\u2014ideal for pilot controls where capacity is less critical. Additionally, this model includes manual override options (D or L control) with a detent mechanism designed primarily for temporary actuation. For environments utilizing phosphate ester fluids, cartridges with EPDM seals are available; however, these seals must not be exposed to petroleum-based fluids as they can degrade. The wet armature design of the valve means that the working fluid surrounds the armature; this is crucial to consider as prolonged energization could lead to fluid degradation at high temperatures. Interchangeability is another key feature of the DMDAXNN928 model\u2014its coils can be swapped with other Sun Series 1 solenoid products and mounted in any direction on the tube. This model also incorporates Sun's floating style construction which minimizes internal binding caused by excessive installation torque or variations in cavity/cartridge machining. With a maximum operating pressure of 5000 psi and a flow capacity of up to 12 gpm (45 L/min), this valve is equipped to handle substantial hydraulic flows efficiently and reliably. Its quick response time (typically 50 ms) and robust construction make it an excellent choice for dynamic systems requiring precise directional control of fluid handling.

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.
