The Sun Hydraulics DMDADAV512 (DMDADAV512) is a high-performance, solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic system applications. It features a direct-acting, balanced spool directional valve mechanism that ensures reliable operation without the need for minimum hydraulic pressure. The model is particularly noted for its fatigue-rated solenoid tube assembly capable of handling pressures up to 5000 psi (350 bar), making it suitable for demanding environments. This valve offers precise control with its closed transition between spool positions B and R, which enhances performance by providing faster and more consistent response times, especially useful in pilot control applications where capacity is less critical. The DMDADAV512 includes manual override options with detent mechanisms (in models equipped with D or L control) designed primarily for temporary actuation, supporting a mechanical life expectancy of around 7,000 cycles. For compatibility with different fluid types, cartridges configured with EPDM seals are recommended when using phosphate ester fluids; however, these should not be used with petroleum-based fluids to avoid seal damage. The valve's design also incorporates a wet armature setup where the working fluid surrounds the armature, an aspect to consider regarding fluid type and operational heat management. Additional features include interchangeable coils compatible with other Sun Series 1 solenoid products and a floating style construction that minimizes internal part binding due to installation variances. With a capacity of 12 gpm (45 L/min) and swift typical response times of 50 ms, along with robust switching capabilities up to 15,000 cycles/hr, the DMDADAV512 is engineered for both efficiency and durability in complex hydraulic systems.

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.
