The Sun Hydraulics DMDAXRV612 (DMDAXRV612) is a solenoid-operated 3-way, 2-position cartridge valve that features a direct-acting, balanced spool design. This valve is specifically engineered for high-performance applications with a fatigue rating for 5000 psi (350 bar) service. It incorporates closed transitions between spools B and R, which helps achieve faster and more consistent response times when used as pilot controls. The DMDAXRV612 operates without requiring a minimum hydraulic pressure, enhancing its versatility in various hydraulic systems. Equipped with interchangeable coils compatible with other Sun Series 1 solenoid products, this valve offers flexibility in maintenance and installation, allowing the coils to be mounted in either direction. The wet armature design ensures that the working fluid surrounds the armature, which is crucial for certain applications but may require consideration of fluid type due to potential heat exposure effects. This model also includes features like a manual override with a detent mechanism designed for temporary actuation and has a mechanical life expectancy of approximately 7,000 cycles. For environments using phosphate ester fluids, cartridges configured with EPDM seals are recommended to avoid damage from petroleum-based substances. The DMDAXRV612 benefits from Sun Hydraulics' floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity/cartridge machining variations. With specifications such as a maximum operating pressure of 5000 psi (350 bar), flow capacity up to 12 gpm (45 L/min), and typical response times around 50 ms, this valve is designed to meet rigorous industrial demands while ensuring reliable operation and longevity.

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.
