The Sun Hydraulics DMDALPN612N (DMDALPN612N) is a solenoid-operated 3-way, 2-position cartridge which functions as a direct-acting, balanced spool directional valve. It is designed for high-performance applications with a fatigue rating for 5000 psi (350 bar) service. This valve features closed transitions between Spools B and R, enhancing performance at the expense of lower capacity, making it ideal for pilot control applications where rapid and consistent response times are crucial. The DMDALPN612N does not require a minimum hydraulic pressure to operate and incorporates manual overrides with detent mechanisms designed for temporary actuation. These overrides have a mechanical life expectancy of about 7,000 cycles. The valve's compatibility with EPDM seals makes it suitable for use with phosphate ester fluids, although exposure to petroleum-based fluids should be avoided as they can damage the seals. This model utilizes a wet armature design where the working fluid surrounds the armature, potentially affecting performance if the coil remains energized over extended periods. The interchangeable coils with other Sun Series 1 solenoid products offer flexibility in mounting direction. Additionally, the construction incorporates Sun's floating style to minimize internal parts binding due to excessive installation torque or variations in cavity/cartridge machining. Key specifications include a flow capacity of 12 gpm (45 L/min), maximum operating pressure of 5000 psi (350 bar), typical response time of 50 ms, and maximum switching frequency of 15,000 cycles/hr. The manual override requires minimal force and has a stroke length suited for precise control adjustments. The compact design includes a .75 inch (19 mm) solenoid tube diameter and weighs only .60 lb (0,30 kg), ensuring easy installation and handling in various hydraulic systems configurations.

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.
