The Sun Hydraulics DMDAXAN912N (DMDAXAN912N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust operation in demanding applications, featuring a fatigue rating for 5000 psi (350 bar) service. The valve's construction includes a solenoid tube assembly that supports intense usage with minimal wear and tear. It operates efficiently without requiring minimum hydraulic pressure, making it suitable for various hydraulic systems. The DMDAXAN912N offers precise control by having closed spools B and R during transitions between positions, enhancing performance at the cost of capacity. This feature is particularly beneficial in pilot control applications where rapid and consistent response times are critical. For manual override situations, the valve includes a detent mechanism designed to sustain approximately 7,000 cycles, ensuring durability and reliability in temporary actuation scenarios. Equipped with EPDM seals, this model is specifically configured for use with phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can degrade the seals. The wet armature design of the valve helps in cooling but requires consideration of fluid properties since prolonged exposure to heat can lead to breakdowns in certain fluid types. This model also benefits from interchangeable coils with other Sun Series 1 solenoid products and features a floating style construction that minimizes internal binding due to installation variances or machining discrepancies. With its compact design offering a flow capacity of up to 12 gpm (45 L/min) and quick response times typically around 50 ms, the DMDAXAN912N is an effective solution for various hydraulic control systems requiring high switching frequencies up to 15,000 cycles per hour.

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.
