The Sun Hydraulics DMDADNV512 (DMDADNV512) is a high-performance solenoid-operated 3-way, 2-position cartridge valve featuring direct-acting, balanced spool directional control. Engineered for precision and durability, this valve is specifically designed to handle a maximum operating pressure of 5000 psi (350 bar) and has a flow capacity of 12 gpm (45 L/min). It is particularly suited for applications requiring robust performance with reliable response times, thanks to its typical response time of 50 ms. The design incorporates a wet armature configuration where the working fluid surrounds the armature, enhancing heat management during prolonged coil energization but requiring careful selection of fluid to avoid breakdown and varnish formation. The valve's construction utilizes Sun's floating style to minimize internal parts binding, which can result from excessive installation torque or cavity/cartridge machining variations. Moreover, the DMDADNV512 features interchangeable coils compatible with other Sun Series 1 solenoid products and supports manual override options with a detent mechanism designed for temporary actuation. The manual override has an expected mechanical life of approximately 7,000 cycles. This valve is also equipped with EPDM seals suitable for systems using phosphate ester fluids, ensuring compatibility and longevity in specific operational environments. This model's robust design includes features like a maximum leakage rate at 110 SUS (24 cSt) of only 5 in\u00b3/min at 3000 psi (80 cc/min at 210 bar), showcasing its efficiency in maintaining system integrity under high-pressure conditions. The versatility in mounting options and compatibility with various fluids makes it an ideal choice for specialized hydraulic applications where precision and reliability are paramount.

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.
