The Sun Hydraulics DMDAXRV512 (DMDAXRV512) is a solenoid-operated 3-way, 2-position cartridge valve that offers precise control in hydraulic systems. This direct-acting, balanced spool directional valve is designed with a fatigue rating suitable for 5000 psi (350 bar) service, ensuring reliability under high-pressure conditions. The valve features closed transitions between Spools B and R, optimizing performance by providing faster and more consistent response times, especially suitable for applications requiring pilot controls. The DMDAXRV512 operates without the need for minimum hydraulic pressure, enhancing its versatility across various hydraulic applications. It incorporates manual override options with a detent mechanism intended for temporary actuation, which has a mechanical life expectancy of about 7,000 cycles. The valve's compatibility with EPDM seals makes it appropriate for systems using phosphate ester fluids; however, it should not be exposed to petroleum-based fluids as they can damage the seals. This model utilizes a wet armature design where the working fluid surrounds the armature. This design consideration is crucial when the coil is energized for extended periods since some fluids may degrade under prolonged exposure to heat. For maintenance and customization, the coils of this valve are interchangeable with other Sun Series 1 solenoid products and can be mounted in either direction to accommodate different system configurations. Additional features include Sun's floating style construction which minimizes internal parts binding due to installation torque or cavity/cartridge machining variations. The DMDAXRV512 supports up to 12 gpm (45 L/min) capacity and allows a maximum operating pressure of 5000 psi (350 bar), with typical response times around 50 ms and maximum valve leakage at 5 in\u00b3/min at 3000 psi. Its robust design and versatile specifications make it an ideal choice for sophisticated hydraulic systems requiring reliable directional control.

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.
