The Sun Hydraulics DMDAXBN612N (DMDAXBN612N) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed to operate efficiently with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of 12 gpm (45 L/min). It features a fatigue-rated solenoid tube assembly suitable for demanding applications. The valve offers closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, particularly when used as pilot controls. This model is directly actuated and does not require minimum hydraulic pressure for operation. It includes options for manual overrides with a detent mechanism designed for temporary actuation; these are expected to last approximately 7,000 cycles mechanically. The DMDAXBN612N is equipped with EPDM seals intended specifically for systems using phosphate ester fluids; however, these seals must avoid exposure to petroleum-based substances which could cause damage. Additionally, the wet armature design of this valve means that the working fluid surrounds the armature which can affect fluid integrity if exposed to heat for extended periods. This model also benefits from interchangeable coils compatible with other Sun Series 1 solenoid products and incorporates Sun's floating style construction which minimizes internal part binding due to installation issues or cavity/cartridge machining variations. This product is ideal for applications requiring robust control with reliable switching capabilities under high-pressure conditions. Its quick response time (typically 50 ms) and ability to handle up to 15,000 switching cycles per hour make it an excellent choice for sophisticated hydraulic systems needing precise flow management.

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.
