The Sun Hydraulics DMDAXRV912N (DMDAXRV912N) 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 robust solenoid tube assembly that is fatigue rated for demanding applications, ensuring reliability under continuous operation. The DMDAXRV912N valve offers closed transitions between positions B and R, which enhances performance by providing faster and more consistent response times, making it ideal for pilot control applications where capacity is less critical. The valve operates without the need for minimum hydraulic pressure, allowing for versatile usage in various hydraulic systems. This model includes options for manual override controls (D, L, and T types), which are primarily intended for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. The valve also incorporates EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can degrade. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products and a wet armature design to accommodate the working fluid around the armature. The design also incorporates Sun's floating style construction to minimize internal parts binding due to installation torque or machining variations. This product is engineered to deliver high switching frequencies up to 15,000 cycles per hour and has a typical response time of 50 ms.

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.
