The Sun Hydraulics DMDAXPN928 (DMDAXPN928) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of up to 12 gpm (45 L/min). It features a fatigue-rated solenoid tube assembly suitable for demanding applications. The valve's spools, B and R, remain closed during transitions between positions to enhance performance despite sacrificing some capacity. This model is particularly effective when used as pilot controls due to its closed transition design, delivering faster and more consistent response times without requiring minimum hydraulic pressure for operation. The manual override in models equipped with D or L control uses a detent mechanism intended for temporary actuation, supporting approximately 7,000 mechanical life cycles. The DMDAXPN928 incorporates EPDM seals suitable for systems utilizing phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances which can cause damage. Its wet armature design allows the working fluid to surround the armature, potentially affecting fluid integrity under prolonged energization. Interchangeable coils with other Sun Series 1 solenoid products offer flexibility in mounting orientation. The valve also benefits from Sun\u2019s floating style construction which minimizes internal parts binding due to installation torque or machining variations of the cavity/cartridge system. This robust construction coupled with its advanced design features make the DMDAXPN928 an ideal choice for various hydraulic control applications requiring reliable and precise performance.

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.
