The Sun Hydraulics DMDAXNV912 (DMDAXNV912) 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 capable of handling pressures up to 5000 psi (350 bar). The valve is particularly noted for its closed transition spools B and R, which enhance performance by ensuring faster and more consistent response times during the shift from one position to another. This characteristic makes the valve ideal for applications where rapid actuation and reliability are critical, such as in pilot control setups. The DMDAXNV912 operates without the need for minimum hydraulic pressure, facilitating its use in a variety of system configurations. It incorporates a wet armature design, allowing the working fluid to cool the armature but requiring consideration of fluid characteristics due to potential heat-related degradation. The valve's manual override feature is equipped with a detent mechanism designed for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. For compatibility with different system fluids, cartridges configured with EPDM seals are recommended for use with phosphate ester fluids; however, these should not be used with petroleum-based fluids as they can damage the seals. Additionally, this model supports interchangeable coils from other Sun Series 1 solenoid products and features Sun\u2019s floating style construction to minimize internal part binding caused by installation torque or machining variations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, and maximum operating pressure of 5000 psi (350 bar). The DMDAXNV912 is built to accommodate frequent switching, up to 15,000 cycles per hour, making it suitable for systems requiring high cycling frequency alongside robust performance and reliability.

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.
