The Sun Hydraulics DMDADNV712N (DMDADNV712N) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for robust hydraulic control in various applications. This direct-acting, balanced spool directional valve is particularly noted for its fatigue-rated solenoid tube assembly, capable of handling pressures up to 5000 psi (350 bar). It features a closed transition between Spools B and R, enhancing performance by providing faster and more consistent response times, especially suitable for pilot control applications where capacity is less critical. The DMDADNV712N operates without the need for minimum hydraulic pressure, offering flexibility in installation and use. It includes options for manual overrides with detent mechanisms designed for temporary actuation; these mechanisms have a mechanical life expectancy of about 7,000 cycles. The valve also accommodates EPDM seals suitable for systems using phosphate ester fluids; however, these seals must not be exposed to petroleum-based fluids as they could be damaged. This model employs a wet armature design where the working fluid surrounds the armature which could be pertinent in scenarios where the coil remains energized over extended periods \u2014 potentially leading to breakdowns in certain fluid types. The interchangeable coils compatible with other Sun Series 1 solenoid products add to the versatility of this unit. Additionally, it incorporates Sun's floating style construction which minimizes internal part binding due to excessive installation torque or cavity/cartridge machining variations. Technical specifications include a flow capacity of 12 gpm (45 L/min), typical response time of 50 ms, maximum operating pressure of 5000 psi (350 bar), and switching frequency up to 15,000 cycles/hr. The manual override requires minimal force and offers precise control with its small stroke length. This compact yet robust model weighs only about 0.60 lb (0.30 kg), making it an efficient choice for space-conscious configurations requiring reliable hydraulic 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.
