The Sun Hydraulics DMDATAV712 (DMDATAV712) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic fluid direction control in various applications. Featuring a direct-acting, balanced spool design, this valve ensures reliable operation with no minimum hydraulic pressure required. It is particularly suitable for pilot control applications due to its closed transitions between spool positions, which enhance response times and consistency without compromising performance limits. Engineered for durability, the DMDATAV712 includes a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it robust enough for demanding environments. The manual override feature, available in models with D or L control, is designed with a detent mechanism intended for temporary actuation, supporting approximately 7,000 cycles of mechanical life expectancy. Additionally, this valve model utilizes EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they can cause damage. The DMDATAV712 also benefits from Sun Hydraulics' innovative wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil is energized over extended periods as it helps manage heat dissipation but requires careful selection of fluid types to avoid breakdown and varnish formation. With interchangeable coils compatible with other Sun Series 1 solenoid products and a floating style construction that minimizes internal parts binding, the valve offers both versatility and reliability. Key specifications include a maximum operating pressure of 5000 psi (350 bar), flow capacity of up to 12 gpm (45 L/min), and swift response times typically around 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.
