The Sun Hydraulics DMDADRV712N (DMDADRV712N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve specifically designed for robust and efficient hydraulic system operations. This direct-acting, balanced spool directional valve features a fatigue rating for 5000 psi (350 bar) service, making it suitable for high-pressure applications. The unique construction of the valve ensures closed transitions between Spools B and R, enhancing performance by providing faster and more consistent response times especially in pilot control applications where capacity is less critical. Engineered with a wet armature design, the DMDADRV712N allows the working fluid to surround the armature, which is particularly useful in systems that may experience prolonged coil energization. However, users should note that certain fluids like water-glycol mixtures may degrade under sustained high temperatures. The valve supports a maximum flow rate of 12 gpm (45 L/min) and incorporates interchangeable coils compatible with other Sun Series 1 solenoid products. These coils can be mounted in either direction on the tube for flexibility in installation. Additionally, this model employs Sun\u2019s floating style construction which minimizes internal parts binding due to excessive installation torque or cavity/cartridge machining variations. The manual override feature of this model requires minimal force and is designed primarily for temporary actuation with a mechanical life expectancy of approximately 7,000 cycles. Users should also be aware that cartridges configured with EPDM seals are intended for use with phosphate ester fluids only as exposure to petroleum-based fluids will damage the seals. For ease of maintenance and replacement, the DMDADRV712N offers a straightforward approach with its common cavity type T11A and standard Viton seal kits available for both cartridge and coil components. This precision-engineered valve is an essential component for systems requiring reliable directional control in a compact form factor.

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.
