The Sun Hydraulics DMDATNN612 (DMDATNN612) is a high-performance solenoid-operated 3-way, 2-position cartridge valve designed for precise hydraulic control. Featuring a direct-acting, balanced spool configuration, this valve ensures reliable operation without the need for minimum hydraulic pressure. It is particularly noted for its closed transition between spool positions B and R, enhancing performance by ensuring faster and more consistent response times ideal for pilot control applications where capacity is less critical. This model boasts robust construction with a solenoid tube assembly that is fatigue rated for up to 5000 psi (350 bar), making it suitable for demanding applications. The valve has a maximum flow capacity of 12 gpm (45 L/min) and can handle maximum operating pressures up to 5000 psi (350 bar). It offers swift response times typically around 50 ms and maintains tight leakage control not exceeding 5 in\u00b3/min at 3000 psi. Additionally, the DMDATNN612 features interchangeable coils compatible with other Sun Series 1 solenoid products, which can be mounted in either direction on the tube. The wet armature design of the valve allows the working fluid to surround the armature, which should be considered in applications where the coil may remain energized for extended periods. Manual override options are available with a mechanical life expectancy of about 7,000 cycles, providing temporary actuation when needed. The construction incorporates Sun\u2019s floating style to minimize internal parts binding due to installation torque or cavity/cartridge machining variations. This model uses EPDM seals suitable for systems utilizing phosphate ester fluids; however, exposure to petroleum-based fluids should be avoided as it can damage the seals. For ease of installation and maintenance, this valve features a standard T11A cavity and requires an installation torque of between 30 - 35 lbf.ft (41 - 47 Nm).

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.
