The Sun Hydraulics DMDALRN612N (DMDALRN612N) is a solenoid-operated 3-way, 2-position cartridge valve designed for high-performance hydraulic systems. This direct-acting, balanced spool directional valve features a fatigue rating of 5000 psi (350 bar), ensuring durability and reliability under demanding conditions. The valve is notable for its 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 DMDALRN612N operates without requiring a minimum hydraulic pressure, making it versatile for various hydraulic circuits. It includes manual override options with the D or L control featuring a detent mechanism designed primarily for temporary actuation. The mechanical life expectancy of this manual control assembly is approximately 7,000 cycles. Configurations with EPDM seals are specifically intended for use with phosphate ester fluids; however, these should not be exposed to petroleum-based fluids as it would compromise the seal integrity. Additionally, the valve employs a wet armature design where the working fluid surrounds the armature which can be susceptible to heat during prolonged coil energization. This factor needs consideration in systems using fluids like water-glycol mixtures which may degrade under high temperatures. The interchangeable coils compatible with other Sun Series 1 solenoid products add to its adaptability and ease of use. This model also incorporates Sun\u2019s floating style construction which minimizes internal parts binding caused by excessive installation torque or cavity-cartridge machining variations, enhancing operational consistency and lifespan. With a maximum flow capacity of 12 gpm (45 L/min) and quick response times typically around 50 ms, the DMDALRN612N is an efficient solution for advanced hydraulic setups requiring precise control and robust performance.

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.
