The Sun Hydraulics DMDADAN612N (DMDADAN612N) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue-rated solenoid tube assembly for service up to 5000 psi (350 bar), ensuring reliability and durability under demanding conditions. The valve's unique design includes closed transitions between Spools B and R, optimizing performance by enhancing response times and consistency, particularly in pilot control applications where capacity is less critical. This model is equipped with manual override options including D, L, or T control types, each offering a mechanical life expectancy of approximately 7,000 cycles. The manual override feature is specifically designed for temporary actuation, adding an extra layer of operational flexibility. Additionally, the DMDADAN612N utilizes EPDM seals suitable for use with phosphate ester fluids; however, these seals are not compatible with petroleum-based fluids which can cause damage. The wet armature design of this valve allows the working fluid to surround the armature, a factor that needs consideration regarding heat generation if the coil remains energized over extended periods. This design choice impacts fluid integrity over time but provides significant benefits in terms of valve responsiveness and longevity. Furthermore, the coils used in this model are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different system configurations. Incorporating Sun\u2019s floating style construction, the DMDADAN612N minimizes internal parts binding caused by excessive installation torque or variations in cavity/cartridge machining. This feature ensures smoother operation and extends the operational lifespan of the valve under varied installation conditions. With a capacity of 12 gpm (45 L/min) and swift response times typically around 50 ms, this valve is an effective solution for advanced hydraulic circuitry requiring precise control and robust 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.
