The Sun Hydraulics DMDAXNV712N (DMDAXNV712N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve, designed for robust and efficient hydraulic control. Featuring a direct-acting, balanced spool directional valve mechanism, this model ensures reliable operation without the need for minimum hydraulic pressure. Its construction includes a fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for demanding applications. The DMDAXNV712N valve offers precise control with closed transitions between Spools B and R, enhancing performance by ensuring faster and more consistent response times, especially useful in pilot control setups. The manual override feature is equipped with a detent mechanism intended for temporary actuation, with the mechanical life expectancy of the manual control assembly around 7,000 cycles. Additionally, this model uses EPDM seals recommended for systems utilizing phosphate ester fluids; however, these seals are susceptible to damage when exposed to petroleum-based fluids. This valve also incorporates a wet armature design allowing the working fluid to surround the armature which helps in managing heat during prolonged coil energization but can degrade certain types of hydraulic fluids over time. The interchangeable coils compatible with other Sun Series 1 solenoid products offer flexible mounting options. Furthermore, the floating style construction minimizes internal part binding due to installation torque or cavity/cartridge machining variations. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum valve leakage at 110 SUS (24 cSt) rated at 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar). The switching frequency capability reaches up to 15,000 cycles/hr. This compact valve model weighs approximately 0.60 lbs (0.30 kg) and requires an installation torque between 30 - 35 lbf.ft (41 - 47 Nm).

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.
