The Sun Hydraulics DMDAXAV512 (DMDAXAV512) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. This direct-acting, balanced spool directional valve is engineered to function efficiently with a maximum operating pressure of 5000 psi (350 bar) and a flow capacity of up to 12 gpm (45 L/min). The valve features closed transitions between its two positions (Spools B and R), optimizing performance by ensuring faster and more consistent response times, particularly suitable for applications requiring precise pilot controls. The DMDAXAV512 is equipped with a fatigue-rated solenoid tube assembly, making it robust for demanding applications. It does not require a minimum hydraulic pressure to operate, enhancing its versatility across various hydraulic systems. The model can be fitted with EPDM seals specifically for use with phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could degrade. Further enhancing its utility, the valve incorporates interchangeable coils from the Sun Series 1 solenoid products and features a wet armature design where the working fluid surrounds the armature. This design consideration is crucial as prolonged energization can lead to heat buildup affecting certain fluid types. Additionally, the DMDAXAV512 utilizes Sun's floating style construction which minimizes internal parts binding due to installation variances or cavity/cartridge machining inaccuracies. This model also provides manual override options with a detent mechanism designed for temporary actuation and has an expected mechanical life of approximately 7,000 cycles. With its robust build and versatile design features, the Sun Hydraulics DMDAXAV512 is an excellent choice for sophisticated hydraulic control in various applications needing reliable performance under high-pressure conditions.

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.
