The Sun Hydraulics DMDAXBV712 (DMDAXBV712) is a high-performance solenoid-operated 3-way, 2-position cartridge valve. This direct-acting, balanced spool directional valve is designed for robust operation, featuring a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar) service. It ensures reliable switching with closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times, particularly suitable for applications as pilot controls where capacity is less critical. The DMDAXBV712 operates without requiring a minimum hydraulic pressure, making it versatile for various hydraulic systems. The manual override included in models with D or L control is designed for temporary actuation only, with a mechanical life expectancy of around 7,000 cycles. It's important to note that cartridges configured with EPDM seals should be used exclusively in systems utilizing phosphate ester fluids to avoid damage from petroleum-based substances. This valve incorporates a wet armature design where the working fluid surrounds the armature; this aspect needs consideration regarding the type of fluid used due to potential breakdowns at high temperatures. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in maintenance and replacement processes. Additionally, the floating style construction of the valve minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. Key specifications include a maximum flow capacity of 12 gpm (45 L/min), typical response times of 50 ms, and maximum operating pressures up to 5000 psi (350 bar). With its robust construction and advanced design features, the Sun Hydraulics DMDAXBV712 valve offers reliability and efficiency for demanding hydraulic applications.

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.
